+/**
+ * @ngdoc service
+ * @name $animateCss
+ * @kind object
+ *
+ * @description
+ * The `$animateCss` service is a useful utility to trigger customized CSS-based transitions/keyframes
+ * from a JavaScript-based animation or directly from a directive. The purpose of `$animateCss` is NOT
+ * to side-step how `$animate` and ngAnimate work, but the goal is to allow pre-existing animations or
+ * directives to create more complex animations that can be purely driven using CSS code.
+ *
+ * Note that only browsers that support CSS transitions and/or keyframe animations are capable of
+ * rendering animations triggered via `$animateCss` (bad news for IE9 and lower).
+ *
+ * ## Usage
+ * Once again, `$animateCss` is designed to be used inside of a registered JavaScript animation that
+ * is powered by ngAnimate. It is possible to use `$animateCss` directly inside of a directive, however,
+ * any automatic control over cancelling animations and/or preventing animations from being run on
+ * child elements will not be handled by Angular. For this to work as expected, please use `$animate` to
+ * trigger the animation and then setup a JavaScript animation that injects `$animateCss` to trigger
+ * the CSS animation.
+ *
+ * The example below shows how we can create a folding animation on an element using `ng-if`:
+ *
+ * ```html
+ * <!-- notice the `fold-animation` CSS class -->
+ * <div ng-if="onOff" class="fold-animation">
+ *   This element will go BOOM
+ * </div>
+ * <button ng-click="onOff=true">Fold In</button>
+ * ```
+ *
+ * Now we create the **JavaScript animation** that will trigger the CSS transition:
+ *
+ * ```js
+ * ngModule.animation('.fold-animation', ['$animateCss', function($animateCss) {
+ *   return {
+ *     enter: function(element, doneFn) {
+ *       var height = element[0].offsetHeight;
+ *       return $animateCss(element, {
+ *         from: { height:'0px' },
+ *         to: { height:height + 'px' },
+ *         duration: 1 // one second
+ *       });
+ *     }
+ *   }
+ * }]);
+ * ```
+ *
+ * ## More Advanced Uses
+ *
+ * `$animateCss` is the underlying code that ngAnimate uses to power **CSS-based animations** behind the scenes. Therefore CSS hooks
+ * like `.ng-EVENT`, `.ng-EVENT-active`, `.ng-EVENT-stagger` are all features that can be triggered using `$animateCss` via JavaScript code.
+ *
+ * This also means that just about any combination of adding classes, removing classes, setting styles, dynamically setting a keyframe animation,
+ * applying a hardcoded duration or delay value, changing the animation easing or applying a stagger animation are all options that work with
+ * `$animateCss`. The service itself is smart enough to figure out the combination of options and examine the element styling properties in order
+ * to provide a working animation that will run in CSS.
+ *
+ * The example below showcases a more advanced version of the `.fold-animation` from the example above:
+ *
+ * ```js
+ * ngModule.animation('.fold-animation', ['$animateCss', function($animateCss) {
+ *   return {
+ *     enter: function(element, doneFn) {
+ *       var height = element[0].offsetHeight;
+ *       return $animateCss(element, {
+ *         addClass: 'red large-text pulse-twice',
+ *         easing: 'ease-out',
+ *         from: { height:'0px' },
+ *         to: { height:height + 'px' },
+ *         duration: 1 // one second
+ *       });
+ *     }
+ *   }
+ * }]);
+ * ```
+ *
+ * Since we're adding/removing CSS classes then the CSS transition will also pick those up:
+ *
+ * ```css
+ * /&#42; since a hardcoded duration value of 1 was provided in the JavaScript animation code,
+ * the CSS classes below will be transitioned despite them being defined as regular CSS classes &#42;/
+ * .red { background:red; }
+ * .large-text { font-size:20px; }
+ *
+ * /&#42; we can also use a keyframe animation and $animateCss will make it work alongside the transition &#42;/
+ * .pulse-twice {
+ *   animation: 0.5s pulse linear 2;
+ *   -webkit-animation: 0.5s pulse linear 2;
+ * }
+ *
+ * @keyframes pulse {
+ *   from { transform: scale(0.5); }
+ *   to { transform: scale(1.5); }
+ * }
+ *
+ * @-webkit-keyframes pulse {
+ *   from { -webkit-transform: scale(0.5); }
+ *   to { -webkit-transform: scale(1.5); }
+ * }
+ * ```
+ *
+ * Given this complex combination of CSS classes, styles and options, `$animateCss` will figure everything out and make the animation happen.
+ *
+ * ## How the Options are handled
+ *
+ * `$animateCss` is very versatile and intelligent when it comes to figuring out what configurations to apply to the element to ensure the animation
+ * works with the options provided. Say for example we were adding a class that contained a keyframe value and we wanted to also animate some inline
+ * styles using the `from` and `to` properties.
+ *
+ * ```js
+ * var animator = $animateCss(element, {
+ *   from: { background:'red' },
+ *   to: { background:'blue' }
+ * });
+ * animator.start();
+ * ```
+ *
+ * ```css
+ * .rotating-animation {
+ *   animation:0.5s rotate linear;
+ *   -webkit-animation:0.5s rotate linear;
+ * }
+ *
+ * @keyframes rotate {
+ *   from { transform: rotate(0deg); }
+ *   to { transform: rotate(360deg); }
+ * }
+ *
+ * @-webkit-keyframes rotate {
+ *   from { -webkit-transform: rotate(0deg); }
+ *   to { -webkit-transform: rotate(360deg); }
+ * }
+ * ```
+ *
+ * The missing pieces here are that we do not have a transition set (within the CSS code nor within the `$animateCss` options) and the duration of the animation is
+ * going to be detected from what the keyframe styles on the CSS class are. In this event, `$animateCss` will automatically create an inline transition
+ * style matching the duration detected from the keyframe style (which is present in the CSS class that is being added) and then prepare both the transition
+ * and keyframe animations to run in parallel on the element. Then when the animation is underway the provided `from` and `to` CSS styles will be applied
+ * and spread across the transition and keyframe animation.
+ *
+ * ## What is returned
+ *
+ * `$animateCss` works in two stages: a preparation phase and an animation phase. Therefore when `$animateCss` is first called it will NOT actually
+ * start the animation. All that is going on here is that the element is being prepared for the animation (which means that the generated CSS classes are
+ * added and removed on the element). Once `$animateCss` is called it will return an object with the following properties:
+ *
+ * ```js
+ * var animator = $animateCss(element, { ... });
+ * ```
+ *
+ * Now what do the contents of our `animator` variable look like:
+ *
+ * ```js
+ * {
+ *   // starts the animation
+ *   start: Function,
+ *
+ *   // ends (aborts) the animation
+ *   end: Function
+ * }
+ * ```
+ *
+ * To actually start the animation we need to run `animation.start()` which will then return a promise that we can hook into to detect when the animation ends.
+ * If we choose not to run the animation then we MUST run `animation.end()` to perform a cleanup on the element (since some CSS classes and styles may have been
+ * applied to the element during the preparation phase). Note that all other properties such as duration, delay, transitions and keyframes are just properties
+ * and that changing them will not reconfigure the parameters of the animation.
+ *
+ * ### runner.done() vs runner.then()
+ * It is documented that `animation.start()` will return a promise object and this is true, however, there is also an additional method available on the
+ * runner called `.done(callbackFn)`. The done method works the same as `.finally(callbackFn)`, however, it does **not trigger a digest to occur**.
+ * Therefore, for performance reasons, it's always best to use `runner.done(callback)` instead of `runner.then()`, `runner.catch()` or `runner.finally()`
+ * unless you really need a digest to kick off afterwards.
+ *
+ * Keep in mind that, to make this easier, ngAnimate has tweaked the JS animations API to recognize when a runner instance is returned from $animateCss
+ * (so there is no need to call `runner.done(doneFn)` inside of your JavaScript animation code).
+ * Check the {@link ngAnimate.$animateCss#usage animation code above} to see how this works.
+ *
+ * @param {DOMElement} element the element that will be animated
+ * @param {object} options the animation-related options that will be applied during the animation
+ *
+ * * `event` - The DOM event (e.g. enter, leave, move). When used, a generated CSS class of `ng-EVENT` and `ng-EVENT-active` will be applied
+ * to the element during the animation. Multiple events can be provided when spaces are used as a separator. (Note that this will not perform any DOM operation.)
+ * * `structural` - Indicates that the `ng-` prefix will be added to the event class. Setting to `false` or omitting will turn `ng-EVENT` and
+ * `ng-EVENT-active` in `EVENT` and `EVENT-active`. Unused if `event` is omitted.
+ * * `easing` - The CSS easing value that will be applied to the transition or keyframe animation (or both).
+ * * `transitionStyle` - The raw CSS transition style that will be used (e.g. `1s linear all`).
+ * * `keyframeStyle` - The raw CSS keyframe animation style that will be used (e.g. `1s my_animation linear`).
+ * * `from` - The starting CSS styles (a key/value object) that will be applied at the start of the animation.
+ * * `to` - The ending CSS styles (a key/value object) that will be applied across the animation via a CSS transition.
+ * * `addClass` - A space separated list of CSS classes that will be added to the element and spread across the animation.
+ * * `removeClass` - A space separated list of CSS classes that will be removed from the element and spread across the animation.
+ * * `duration` - A number value representing the total duration of the transition and/or keyframe (note that a value of 1 is 1000ms). If a value of `0`
+ * is provided then the animation will be skipped entirely.
+ * * `delay` - A number value representing the total delay of the transition and/or keyframe (note that a value of 1 is 1000ms). If a value of `true` is
+ * used then whatever delay value is detected from the CSS classes will be mirrored on the elements styles (e.g. by setting delay true then the style value
+ * of the element will be `transition-delay: DETECTED_VALUE`). Using `true` is useful when you want the CSS classes and inline styles to all share the same
+ * CSS delay value.
+ * * `stagger` - A numeric time value representing the delay between successively animated elements
+ * ({@link ngAnimate#css-staggering-animations Click here to learn how CSS-based staggering works in ngAnimate.})
+ * * `staggerIndex` - The numeric index representing the stagger item (e.g. a value of 5 is equal to the sixth item in the stagger; therefore when a
+ *   `stagger` option value of `0.1` is used then there will be a stagger delay of `600ms`)
+ * * `applyClassesEarly` - Whether or not the classes being added or removed will be used when detecting the animation. This is set by `$animate` when enter/leave/move animations are fired to ensure that the CSS classes are resolved in time. (Note that this will prevent any transitions from occurring on the classes being added and removed.)
+ * * `cleanupStyles` - Whether or not the provided `from` and `to` styles will be removed once
+ *    the animation is closed. This is useful for when the styles are used purely for the sake of
+ *    the animation and do not have a lasting visual effect on the element (e.g. a collapse and open animation).
+ *    By default this value is set to `false`.
+ *
+ * @return {object} an object with start and end methods and details about the animation.
+ *
+ * * `start` - The method to start the animation. This will return a `Promise` when called.
+ * * `end` - This method will cancel the animation and remove all applied CSS classes and styles.

+/**
+ * @ngdoc module
+ * @name ngAnimate
+ * @description
+ *
+ * The `ngAnimate` module provides support for CSS-based animations (keyframes and transitions) as well as JavaScript-based animations via
+ * callback hooks. Animations are not enabled by default, however, by including `ngAnimate` the animation hooks are enabled for an Angular app.
+ *
+ * <div doc-module-components="ngAnimate"></div>
+ *
+ * # Usage
+ * Simply put, there are two ways to make use of animations when ngAnimate is used: by using **CSS** and **JavaScript**. The former works purely based
+ * using CSS (by using matching CSS selectors/styles) and the latter triggers animations that are registered via `module.animation()`. For
+ * both CSS and JS animations the sole requirement is to have a matching `CSS class` that exists both in the registered animation and within
+ * the HTML element that the animation will be triggered on.
+ *
+ * ## Directive Support
+ * The following directives are "animation aware":
+ *
+ * | Directive                                                                                                | Supported Animations                                                     |

+ * | {@link ngRoute.directive:ngView#animations ngView}                                                       | enter and leave                                                          |
+ * | {@link ng.directive:ngInclude#animations ngInclude}                                                      | enter and leave                                                          |
+ * | {@link ng.directive:ngSwitch#animations ngSwitch}                                                        | enter and leave                                                          |
+ * | {@link ng.directive:ngIf#animations ngIf}                                                                | enter and leave                                                          |
+ * | {@link ng.directive:ngClass#animations ngClass}                                                          | add and remove (the CSS class(es) present)                               |
+ * | {@link ng.directive:ngShow#animations ngShow} & {@link ng.directive:ngHide#animations ngHide}            | add and remove (the ng-hide class value)                                 |
+ * | {@link ng.directive:form#animation-hooks form} & {@link ng.directive:ngModel#animation-hooks ngModel}    | add and remove (dirty, pristine, valid, invalid & all other validations) |
+ * | {@link module:ngMessages#animations ngMessages}                                                          | add and remove (ng-active & ng-inactive)                                 |
+ * | {@link module:ngMessages#animations ngMessage}                                                           | enter and leave                                                          |
+ *
+ * (More information can be found by visiting each the documentation associated with each directive.)
+ *
+ * ## CSS-based Animations
+ *
+ * CSS-based animations with ngAnimate are unique since they require no JavaScript code at all. By using a CSS class that we reference between our HTML
+ * and CSS code we can create an animation that will be picked up by Angular when an the underlying directive performs an operation.
+ *
+ * The example below shows how an `enter` animation can be made possible on an element using `ng-if`:
+ *
+ * ```html
+ * <div ng-if="bool" class="fade">
+ *    Fade me in out
+ * </div>
+ * <button ng-click="bool=true">Fade In!</button>
+ * <button ng-click="bool=false">Fade Out!</button>
+ * ```
+ *
+ * Notice the CSS class **fade**? We can now create the CSS transition code that references this class:
+ *
+ * ```css
+ * /&#42; The starting CSS styles for the enter animation &#42;/
+ * .fade.ng-enter {
+ *   transition:0.5s linear all;
+ *   opacity:0;
+ * }
+ *
+ * /&#42; The finishing CSS styles for the enter animation &#42;/
+ * .fade.ng-enter.ng-enter-active {
+ *   opacity:1;
+ * }
+ * ```
+ *
+ * The key thing to remember here is that, depending on the animation event (which each of the directives above trigger depending on what's going on) two
+ * generated CSS classes will be applied to the element; in the example above we have `.ng-enter` and `.ng-enter-active`. For CSS transitions, the transition
+ * code **must** be defined within the starting CSS class (in this case `.ng-enter`). The destination class is what the transition will animate towards.
+ *
+ * If for example we wanted to create animations for `leave` and `move` (ngRepeat triggers move) then we can do so using the same CSS naming conventions:
+ *
+ * ```css
+ * /&#42; now the element will fade out before it is removed from the DOM &#42;/
+ * .fade.ng-leave {
+ *   transition:0.5s linear all;
+ *   opacity:1;
+ * }
+ * .fade.ng-leave.ng-leave-active {
+ *   opacity:0;
+ * }
+ * ```
+ *
+ * We can also make use of **CSS Keyframes** by referencing the keyframe animation within the starting CSS class:
+ *
+ * ```css
+ * /&#42; there is no need to define anything inside of the destination
+ * CSS class since the keyframe will take charge of the animation &#42;/
+ * .fade.ng-leave {
+ *   animation: my_fade_animation 0.5s linear;
+ *   -webkit-animation: my_fade_animation 0.5s linear;
+ * }
+ *
+ * @keyframes my_fade_animation {
+ *   from { opacity:1; }
+ *   to { opacity:0; }
+ * }
+ *
+ * @-webkit-keyframes my_fade_animation {
+ *   from { opacity:1; }
+ *   to { opacity:0; }
+ * }
+ * ```
+ *
+ * Feel free also mix transitions and keyframes together as well as any other CSS classes on the same element.
+ *
+ * ### CSS Class-based Animations
+ *
+ * Class-based animations (animations that are triggered via `ngClass`, `ngShow`, `ngHide` and some other directives) have a slightly different
+ * naming convention. Class-based animations are basic enough that a standard transition or keyframe can be referenced on the class being added
+ * and removed.
+ *
+ * For example if we wanted to do a CSS animation for `ngHide` then we place an animation on the `.ng-hide` CSS class:
+ *
+ * ```html
+ * <div ng-show="bool" class="fade">
+ *   Show and hide me
+ * </div>
+ * <button ng-click="bool=!bool">Toggle</button>
+ *
+ * <style>
+ * .fade.ng-hide {
+ *   transition:0.5s linear all;
+ *   opacity:0;
+ * }
+ * </style>
+ * ```
+ *
+ * All that is going on here with ngShow/ngHide behind the scenes is the `.ng-hide` class is added/removed (when the hidden state is valid). Since
+ * ngShow and ngHide are animation aware then we can match up a transition and ngAnimate handles the rest.
+ *
+ * In addition the addition and removal of the CSS class, ngAnimate also provides two helper methods that we can use to further decorate the animation
+ * with CSS styles.
+ *
+ * ```html
+ * <div ng-class="{on:onOff}" class="highlight">
+ *   Highlight this box
+ * </div>
+ * <button ng-click="onOff=!onOff">Toggle</button>
+ *
+ * <style>
+ * .highlight {
+ *   transition:0.5s linear all;
+ * }
+ * .highlight.on-add {
+ *   background:white;
+ * }
+ * .highlight.on {
+ *   background:yellow;
+ * }
+ * .highlight.on-remove {
+ *   background:black;
+ * }
+ * </style>
+ * ```
+ *
+ * We can also make use of CSS keyframes by placing them within the CSS classes.
+ *
+ *
+ * ### CSS Staggering Animations
+ * A Staggering animation is a collection of animations that are issued with a slight delay in between each successive operation resulting in a
+ * curtain-like effect. The ngAnimate module (versions >=1.2) supports staggering animations and the stagger effect can be
+ * performed by creating a **ng-EVENT-stagger** CSS class and attaching that class to the base CSS class used for
+ * the animation. The style property expected within the stagger class can either be a **transition-delay** or an
+ * **animation-delay** property (or both if your animation contains both transitions and keyframe animations).
+ *
+ * ```css
+ * .my-animation.ng-enter {
+ *   /&#42; standard transition code &#42;/
+ *   transition: 1s linear all;
+ *   opacity:0;
+ * }
+ * .my-animation.ng-enter-stagger {
+ *   /&#42; this will have a 100ms delay between each successive leave animation &#42;/
+ *   transition-delay: 0.1s;
+ *
+ *   /&#42; As of 1.4.4, this must always be set: it signals ngAnimate
+ *     to not accidentally inherit a delay property from another CSS class &#42;/
+ *   transition-duration: 0s;
+ * }
+ * .my-animation.ng-enter.ng-enter-active {
+ *   /&#42; standard transition styles &#42;/
+ *   opacity:1;
+ * }
+ * ```
+ *
+ * Staggering animations work by default in ngRepeat (so long as the CSS class is defined). Outside of ngRepeat, to use staggering animations
+ * on your own, they can be triggered by firing multiple calls to the same event on $animate. However, the restrictions surrounding this
+ * are that each of the elements must have the same CSS className value as well as the same parent element. A stagger operation
+ * will also be reset if one or more animation frames have passed since the multiple calls to `$animate` were fired.
+ *
+ * The following code will issue the **ng-leave-stagger** event on the element provided:
+ *
+ * ```js
+ * var kids = parent.children();
+ *
+ * $animate.leave(kids[0]); //stagger index=0
+ * $animate.leave(kids[1]); //stagger index=1
+ * $animate.leave(kids[2]); //stagger index=2
+ * $animate.leave(kids[3]); //stagger index=3
+ * $animate.leave(kids[4]); //stagger index=4
+ *
+ * window.requestAnimationFrame(function() {
+ *   //stagger has reset itself
+ *   $animate.leave(kids[5]); //stagger index=0
+ *   $animate.leave(kids[6]); //stagger index=1
+ *
+ *   $scope.$digest();
+ * });
+ * ```
+ *
+ * Stagger animations are currently only supported within CSS-defined animations.
+ *
+ * ### The `ng-animate` CSS class
+ *
+ * When ngAnimate is animating an element it will apply the `ng-animate` CSS class to the element for the duration of the animation.
+ * This is a temporary CSS class and it will be removed once the animation is over (for both JavaScript and CSS-based animations).
+ *
+ * Therefore, animations can be applied to an element using this temporary class directly via CSS.
+ *
+ * ```css
+ * .zipper.ng-animate {
+ *   transition:0.5s linear all;
+ * }
+ * .zipper.ng-enter {
+ *   opacity:0;
+ * }
+ * .zipper.ng-enter.ng-enter-active {
+ *   opacity:1;
+ * }
+ * .zipper.ng-leave {
+ *   opacity:1;
+ * }
+ * .zipper.ng-leave.ng-leave-active {
+ *   opacity:0;
+ * }
+ * ```
+ *
+ * (Note that the `ng-animate` CSS class is reserved and it cannot be applied on an element directly since ngAnimate will always remove
+ * the CSS class once an animation has completed.)
+ *
+ *
+ * ### The `ng-[event]-prepare` class
+ *
+ * This is a special class that can be used to prevent unwanted flickering / flash of content before
+ * the actual animation starts. The class is added as soon as an animation is initialized, but removed
+ * before the actual animation starts (after waiting for a $digest).
+ * It is also only added for *structural* animations (`enter`, `move`, and `leave`).
+ *
+ * In practice, flickering can appear when nesting elements with structural animations such as `ngIf`
+ * into elements that have class-based animations such as `ngClass`.
+ *
+ * ```html
+ * <div ng-class="{red: myProp}">
+ *   <div ng-class="{blue: myProp}">
+ *     <div class="message" ng-if="myProp"></div>
+ *   </div>
+ * </div>
+ * ```
+ *
+ * It is possible that during the `enter` animation, the `.message` div will be briefly visible before it starts animating.
+ * In that case, you can add styles to the CSS that make sure the element stays hidden before the animation starts:
+ *
+ * ```css
+ * .message.ng-enter-prepare {
+ *   opacity: 0;
+ * }
+ *
+ * ```
+ *
+ * ## JavaScript-based Animations
+ *
+ * ngAnimate also allows for animations to be consumed by JavaScript code. The approach is similar to CSS-based animations (where there is a shared
+ * CSS class that is referenced in our HTML code) but in addition we need to register the JavaScript animation on the module. By making use of the
+ * `module.animation()` module function we can register the animation.
+ *
+ * Let's see an example of a enter/leave animation using `ngRepeat`:
+ *
+ * ```html
+ * <div ng-repeat="item in items" class="slide">
+ *   {{ item }}
+ * </div>
+ * ```
+ *
+ * See the **slide** CSS class? Let's use that class to define an animation that we'll structure in our module code by using `module.animation`:
+ *
+ * ```js
+ * myModule.animation('.slide', [function() {
+ *   return {
+ *     // make note that other events (like addClass/removeClass)
+ *     // have different function input parameters
+ *     enter: function(element, doneFn) {
+ *       jQuery(element).fadeIn(1000, doneFn);
+ *
+ *       // remember to call doneFn so that angular
+ *       // knows that the animation has concluded
+ *     },
+ *
+ *     move: function(element, doneFn) {
+ *       jQuery(element).fadeIn(1000, doneFn);
+ *     },
+ *
+ *     leave: function(element, doneFn) {
+ *       jQuery(element).fadeOut(1000, doneFn);
+ *     }
+ *   }
+ * }]);
+ * ```
+ *
+ * The nice thing about JS-based animations is that we can inject other services and make use of advanced animation libraries such as
+ * greensock.js and velocity.js.
+ *
+ * If our animation code class-based (meaning that something like `ngClass`, `ngHide` and `ngShow` triggers it) then we can still define
+ * our animations inside of the same registered animation, however, the function input arguments are a bit different:
+ *
+ * ```html
+ * <div ng-class="color" class="colorful">
+ *   this box is moody
+ * </div>
+ * <button ng-click="color='red'">Change to red</button>
+ * <button ng-click="color='blue'">Change to blue</button>
+ * <button ng-click="color='green'">Change to green</button>
+ * ```
+ *
+ * ```js
+ * myModule.animation('.colorful', [function() {
+ *   return {
+ *     addClass: function(element, className, doneFn) {
+ *       // do some cool animation and call the doneFn
+ *     },
+ *     removeClass: function(element, className, doneFn) {
+ *       // do some cool animation and call the doneFn
+ *     },
+ *     setClass: function(element, addedClass, removedClass, doneFn) {
+ *       // do some cool animation and call the doneFn
+ *     }
+ *   }
+ * }]);
+ * ```
+ *
+ * ## CSS + JS Animations Together
+ *
+ * AngularJS 1.4 and higher has taken steps to make the amalgamation of CSS and JS animations more flexible. However, unlike earlier versions of Angular,
+ * defining CSS and JS animations to work off of the same CSS class will not work anymore. Therefore the example below will only result in **JS animations taking
+ * charge of the animation**:
+ *
+ * ```html
+ * <div ng-if="bool" class="slide">
+ *   Slide in and out
+ * </div>
+ * ```
+ *
+ * ```js
+ * myModule.animation('.slide', [function() {
+ *   return {
+ *     enter: function(element, doneFn) {
+ *       jQuery(element).slideIn(1000, doneFn);
+ *     }
+ *   }
+ * }]);
+ * ```
+ *
+ * ```css
+ * .slide.ng-enter {
+ *   transition:0.5s linear all;
+ *   transform:translateY(-100px);
+ * }
+ * .slide.ng-enter.ng-enter-active {
+ *   transform:translateY(0);
+ * }
+ * ```
+ *
+ * Does this mean that CSS and JS animations cannot be used together? Do JS-based animations always have higher priority? We can make up for the
+ * lack of CSS animations by using the `$animateCss` service to trigger our own tweaked-out, CSS-based animations directly from
+ * our own JS-based animation code:
+ *
+ * ```js
+ * myModule.animation('.slide', ['$animateCss', function($animateCss) {
+ *   return {
+ *     enter: function(element) {
+*        // this will trigger `.slide.ng-enter` and `.slide.ng-enter-active`.
+ *       return $animateCss(element, {
+ *         event: 'enter',
+ *         structural: true
+ *       });
+ *     }
+ *   }
+ * }]);
+ * ```
+ *
+ * The nice thing here is that we can save bandwidth by sticking to our CSS-based animation code and we don't need to rely on a 3rd-party animation framework.
+ *
+ * The `$animateCss` service is very powerful since we can feed in all kinds of extra properties that will be evaluated and fed into a CSS transition or
+ * keyframe animation. For example if we wanted to animate the height of an element while adding and removing classes then we can do so by providing that
+ * data into `$animateCss` directly:
+ *
+ * ```js
+ * myModule.animation('.slide', ['$animateCss', function($animateCss) {
+ *   return {
+ *     enter: function(element) {
+ *       return $animateCss(element, {
+ *         event: 'enter',
+ *         structural: true,
+ *         addClass: 'maroon-setting',
+ *         from: { height:0 },
+ *         to: { height: 200 }
+ *       });
+ *     }
+ *   }
+ * }]);
+ * ```
+ *
+ * Now we can fill in the rest via our transition CSS code:
+ *
+ * ```css
+ * /&#42; the transition tells ngAnimate to make the animation happen &#42;/
+ * .slide.ng-enter { transition:0.5s linear all; }
+ *
+ * /&#42; this extra CSS class will be absorbed into the transition
+ * since the $animateCss code is adding the class &#42;/
+ * .maroon-setting { background:red; }
+ * ```
+ *
+ * And `$animateCss` will figure out the rest. Just make sure to have the `done()` callback fire the `doneFn` function to signal when the animation is over.
+ *
+ * To learn more about what's possible be sure to visit the {@link ngAnimate.$animateCss $animateCss service}.
+ *
+ * ## Animation Anchoring (via `ng-animate-ref`)
+ *
+ * ngAnimate in AngularJS 1.4 comes packed with the ability to cross-animate elements between
+ * structural areas of an application (like views) by pairing up elements using an attribute
+ * called `ng-animate-ref`.
+ *
+ * Let's say for example we have two views that are managed by `ng-view` and we want to show
+ * that there is a relationship between two components situated in within these views. By using the
+ * `ng-animate-ref` attribute we can identify that the two components are paired together and we
+ * can then attach an animation, which is triggered when the view changes.
+ *
+ * Say for example we have the following template code:
+ *
+ * ```html
+ * <!-- index.html -->
+ * <div ng-view class="view-animation">
+ * </div>
+ *
+ * <!-- home.html -->
+ * <a href="#/banner-page">
+ *   <img src="./banner.jpg" class="banner" ng-animate-ref="banner">
+ * </a>
+ *
+ * <!-- banner-page.html -->
+ * <img src="./banner.jpg" class="banner" ng-animate-ref="banner">
+ * ```
+ *
+ * Now, when the view changes (once the link is clicked), ngAnimate will examine the
+ * HTML contents to see if there is a match reference between any components in the view
+ * that is leaving and the view that is entering. It will scan both the view which is being
+ * removed (leave) and inserted (enter) to see if there are any paired DOM elements that
+ * contain a matching ref value.
+ *
+ * The two images match since they share the same ref value. ngAnimate will now create a
+ * transport element (which is a clone of the first image element) and it will then attempt
+ * to animate to the position of the second image element in the next view. For the animation to
+ * work a special CSS class called `ng-anchor` will be added to the transported element.
+ *
+ * We can now attach a transition onto the `.banner.ng-anchor` CSS class and then
+ * ngAnimate will handle the entire transition for us as well as the addition and removal of
+ * any changes of CSS classes between the elements:
+ *
+ * ```css
+ * .banner.ng-anchor {
+ *   /&#42; this animation will last for 1 second since there are
+ *          two phases to the animation (an `in` and an `out` phase) &#42;/
+ *   transition:0.5s linear all;
+ * }
+ * ```
+ *
+ * We also **must** include animations for the views that are being entered and removed
+ * (otherwise anchoring wouldn't be possible since the new view would be inserted right away).
+ *
+ * ```css
+ * .view-animation.ng-enter, .view-animation.ng-leave {
+ *   transition:0.5s linear all;
+ *   position:fixed;
+ *   left:0;
+ *   top:0;
+ *   width:100%;
+ * }
+ * .view-animation.ng-enter {
+ *   transform:translateX(100%);
+ * }
+ * .view-animation.ng-leave,
+ * .view-animation.ng-enter.ng-enter-active {
+ *   transform:translateX(0%);
+ * }
+ * .view-animation.ng-leave.ng-leave-active {
+ *   transform:translateX(-100%);
+ * }
+ * ```
+ *
+ * Now we can jump back to the anchor animation. When the animation happens, there are two stages that occur:
+ * an `out` and an `in` stage. The `out` stage happens first and that is when the element is animated away
+ * from its origin. Once that animation is over then the `in` stage occurs which animates the
+ * element to its destination. The reason why there are two animations is to give enough time
+ * for the enter animation on the new element to be ready.
+ *
+ * The example above sets up a transition for both the in and out phases, but we can also target the out or
+ * in phases directly via `ng-anchor-out` and `ng-anchor-in`.
+ *
+ * ```css
+ * .banner.ng-anchor-out {
+ *   transition: 0.5s linear all;
+ *
+ *   /&#42; the scale will be applied during the out animation,
+ *          but will be animated away when the in animation runs &#42;/
+ *   transform: scale(1.2);
+ * }
+ *
+ * .banner.ng-anchor-in {
+ *   transition: 1s linear all;
+ * }
+ * ```
+ *
+ *
+ *
+ *

+    </file>
+  </example>
+ *
+ * ### How is the element transported?
+ *
+ * When an anchor animation occurs, ngAnimate will clone the starting element and position it exactly where the starting
+ * element is located on screen via absolute positioning. The cloned element will be placed inside of the root element
+ * of the application (where ng-app was defined) and all of the CSS classes of the starting element will be applied. The
+ * element will then animate into the `out` and `in` animations and will eventually reach the coordinates and match
+ * the dimensions of the destination element. During the entire animation a CSS class of `.ng-animate-shim` will be applied
+ * to both the starting and destination elements in order to hide them from being visible (the CSS styling for the class
+ * is: `visibility:hidden`). Once the anchor reaches its destination then it will be removed and the destination element
+ * will become visible since the shim class will be removed.
+ *
+ * ### How is the morphing handled?
+ *
+ * CSS Anchoring relies on transitions and keyframes and the internal code is intelligent enough to figure out
+ * what CSS classes differ between the starting element and the destination element. These different CSS classes
+ * will be added/removed on the anchor element and a transition will be applied (the transition that is provided
+ * in the anchor class). Long story short, ngAnimate will figure out what classes to add and remove which will
+ * make the transition of the element as smooth and automatic as possible. Be sure to use simple CSS classes that
+ * do not rely on DOM nesting structure so that the anchor element appears the same as the starting element (since
+ * the cloned element is placed inside of root element which is likely close to the body element).
+ *
+ * Note that if the root element is on the `<html>` element then the cloned node will be placed inside of body.
+ *
+ *
+ * ## Using $animate in your directive code
+ *
+ * So far we've explored how to feed in animations into an Angular application, but how do we trigger animations within our own directives in our application?
+ * By injecting the `$animate` service into our directive code, we can trigger structural and class-based hooks which can then be consumed by animations. Let's
+ * imagine we have a greeting box that shows and hides itself when the data changes
+ *
+ * ```html
+ * <greeting-box active="onOrOff">Hi there</greeting-box>
+ * ```
+ *
+ * ```js
+ * ngModule.directive('greetingBox', ['$animate', function($animate) {
+ *   return function(scope, element, attrs) {
+ *     attrs.$observe('active', function(value) {
+ *       value ? $animate.addClass(element, 'on') : $animate.removeClass(element, 'on');
+ *     });
+ *   });
+ * }]);
+ * ```
+ *
+ * Now the `on` CSS class is added and removed on the greeting box component. Now if we add a CSS class on top of the greeting box element
+ * in our HTML code then we can trigger a CSS or JS animation to happen.
+ *
+ * ```css
+ * /&#42; normally we would create a CSS class to reference on the element &#42;/
+ * greeting-box.on { transition:0.5s linear all; background:green; color:white; }
+ * ```
+ *
+ * The `$animate` service contains a variety of other methods like `enter`, `leave`, `animate` and `setClass`. To learn more about what's
+ * possible be sure to visit the {@link ng.$animate $animate service API page}.
+ *
+ *
+ * ## Callbacks and Promises
+ *
+ * When `$animate` is called it returns a promise that can be used to capture when the animation has ended. Therefore if we were to trigger
+ * an animation (within our directive code) then we can continue performing directive and scope related activities after the animation has
+ * ended by chaining onto the returned promise that animation method returns.
+ *
+ * ```js
+ * // somewhere within the depths of the directive
+ * $animate.enter(element, parent).then(function() {
+ *   //the animation has completed
+ * });
+ * ```
+ *
+ * (Note that earlier versions of Angular prior to v1.4 required the promise code to be wrapped using `$scope.$apply(...)`. This is not the case
+ * anymore.)
+ *
+ * In addition to the animation promise, we can also make use of animation-related callbacks within our directives and controller code by registering
+ * an event listener using the `$animate` service. Let's say for example that an animation was triggered on our view
+ * routing controller to hook into that:
+ *
+ * ```js
+ * ngModule.controller('HomePageController', ['$animate', function($animate) {
+ *   $animate.on('enter', ngViewElement, function(element) {
+ *     // the animation for this route has completed
+ *   }]);
+ * }])
+ * ```
+ *
+ * (Note that you will need to trigger a digest within the callback to get angular to notice any scope-related changes.)

+/**
+ * @ngdoc service
+ * @name $resource
+ * @requires $http
+ * @requires ng.$log
+ * @requires $q
+ * @requires ng.$timeout
+ *
+ * @description
+ * A factory which creates a resource object that lets you interact with
+ * [RESTful](http://en.wikipedia.org/wiki/Representational_State_Transfer) server-side data sources.
+ *
+ * The returned resource object has action methods which provide high-level behaviors without
+ * the need to interact with the low level {@link ng.$http $http} service.
+ *
+ * Requires the {@link ngResource `ngResource`} module to be installed.
+ *
+ * By default, trailing slashes will be stripped from the calculated URLs,
+ * which can pose problems with server backends that do not expect that
+ * behavior.  This can be disabled by configuring the `$resourceProvider` like
+ * this:
+ *
+ * ```js
+     app.config(['$resourceProvider', function($resourceProvider) {
+       // Don't strip trailing slashes from calculated URLs
+       $resourceProvider.defaults.stripTrailingSlashes = false;
+     }]);
+ * ```
+ *
+ * @param {string} url A parameterized URL template with parameters prefixed by `:` as in
+ *   `/user/:username`. If you are using a URL with a port number (e.g.
+ *   `http://example.com:8080/api`), it will be respected.
+ *
+ *   If you are using a url with a suffix, just add the suffix, like this:
+ *   `$resource('http://example.com/resource.json')` or `$resource('http://example.com/:id.json')`
+ *   or even `$resource('http://example.com/resource/:resource_id.:format')`
+ *   If the parameter before the suffix is empty, :resource_id in this case, then the `/.` will be
+ *   collapsed down to a single `.`.  If you need this sequence to appear and not collapse then you
+ *   can escape it with `/\.`.
+ *
+ * @param {Object=} paramDefaults Default values for `url` parameters. These can be overridden in
+ *   `actions` methods. If a parameter value is a function, it will be called every time
+ *   a param value needs to be obtained for a request (unless the param was overridden). The function
+ *   will be passed the current data value as an argument.
+ *
+ *   Each key value in the parameter object is first bound to url template if present and then any
+ *   excess keys are appended to the url search query after the `?`.
+ *
+ *   Given a template `/path/:verb` and parameter `{verb:'greet', salutation:'Hello'}` results in
+ *   URL `/path/greet?salutation=Hello`.
+ *
+ *   If the parameter value is prefixed with `@`, then the value for that parameter will be
+ *   extracted from the corresponding property on the `data` object (provided when calling a
+ *   "non-GET" action method).
+ *   For example, if the `defaultParam` object is `{someParam: '@someProp'}` then the value of
+ *   `someParam` will be `data.someProp`.
+ *   Note that the parameter will be ignored, when calling a "GET" action method (i.e. an action
+ *   method that does not accept a request body)
+ *
+ * @param {Object.<Object>=} actions Hash with declaration of custom actions that should extend
+ *   the default set of resource actions. The declaration should be created in the format of {@link
+ *   ng.$http#usage $http.config}:
+ *
+ *       {action1: {method:?, params:?, isArray:?, headers:?, ...},
+ *        action2: {method:?, params:?, isArray:?, headers:?, ...},
+ *        ...}
+ *
+ *   Where:
+ *
+ *   - **`action`** – {string} – The name of action. This name becomes the name of the method on
+ *     your resource object.
+ *   - **`method`** – {string} – Case insensitive HTTP method (e.g. `GET`, `POST`, `PUT`,
+ *     `DELETE`, `JSONP`, etc).
+ *   - **`params`** – {Object=} – Optional set of pre-bound parameters for this action. If any of
+ *     the parameter value is a function, it will be called every time when a param value needs to
+ *     be obtained for a request (unless the param was overridden). The function will be passed the
+ *     current data value as an argument.
+ *   - **`url`** – {string} – action specific `url` override. The url templating is supported just
+ *     like for the resource-level urls.
+ *   - **`isArray`** – {boolean=} – If true then the returned object for this action is an array,
+ *     see `returns` section.
+ *   - **`transformRequest`** –
+ *     `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
+ *     transform function or an array of such functions. The transform function takes the http
+ *     request body and headers and returns its transformed (typically serialized) version.
+ *     By default, transformRequest will contain one function that checks if the request data is
+ *     an object and serializes to using `angular.toJson`. To prevent this behavior, set
+ *     `transformRequest` to an empty array: `transformRequest: []`
+ *   - **`transformResponse`** –
+ *     `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
+ *     transform function or an array of such functions. The transform function takes the http
+ *     response body and headers and returns its transformed (typically deserialized) version.
+ *     By default, transformResponse will contain one function that checks if the response looks
+ *     like a JSON string and deserializes it using `angular.fromJson`. To prevent this behavior,
+ *     set `transformResponse` to an empty array: `transformResponse: []`
+ *   - **`cache`** – `{boolean|Cache}` – If true, a default $http cache will be used to cache the
+ *     GET request, otherwise if a cache instance built with
+ *     {@link ng.$cacheFactory $cacheFactory}, this cache will be used for
+ *     caching.
+ *   - **`timeout`** – `{number}` – timeout in milliseconds.<br />
+ *     **Note:** In contrast to {@link ng.$http#usage $http.config}, {@link ng.$q promises} are
+ *     **not** supported in $resource, because the same value would be used for multiple requests.
+ *     If you are looking for a way to cancel requests, you should use the `cancellable` option.
+ *   - **`cancellable`** – `{boolean}` – if set to true, the request made by a "non-instance" call
+ *     will be cancelled (if not already completed) by calling `$cancelRequest()` on the call's
+ *     return value. Calling `$cancelRequest()` for a non-cancellable or an already
+ *     completed/cancelled request will have no effect.<br />
+ *   - **`withCredentials`** - `{boolean}` - whether to set the `withCredentials` flag on the
+ *     XHR object. See
+ *     [requests with credentials](https://developer.mozilla.org/en/http_access_control#section_5)
+ *     for more information.
+ *   - **`responseType`** - `{string}` - see
+ *     [requestType](https://developer.mozilla.org/en-US/docs/DOM/XMLHttpRequest#responseType).
+ *   - **`interceptor`** - `{Object=}` - The interceptor object has two optional methods -
+ *     `response` and `responseError`. Both `response` and `responseError` interceptors get called
+ *     with `http response` object. See {@link ng.$http $http interceptors}.
+ *
+ * @param {Object} options Hash with custom settings that should extend the
+ *   default `$resourceProvider` behavior.  The supported options are:
+ *
+ *   - **`stripTrailingSlashes`** – {boolean} – If true then the trailing
+ *   slashes from any calculated URL will be stripped. (Defaults to true.)
+ *   - **`cancellable`** – {boolean} – If true, the request made by a "non-instance" call will be
+ *   cancelled (if not already completed) by calling `$cancelRequest()` on the call's return value.
+ *   This can be overwritten per action. (Defaults to false.)
+ *
+ * @returns {Object} A resource "class" object with methods for the default set of resource actions
+ *   optionally extended with custom `actions`. The default set contains these actions:
+ *   ```js
+ *   { 'get':    {method:'GET'},
+ *     'save':   {method:'POST'},
+ *     'query':  {method:'GET', isArray:true},
+ *     'remove': {method:'DELETE'},
+ *     'delete': {method:'DELETE'} };
+ *   ```
+ *
+ *   Calling these methods invoke an {@link ng.$http} with the specified http method,
+ *   destination and parameters. When the data is returned from the server then the object is an
+ *   instance of the resource class. The actions `save`, `remove` and `delete` are available on it
+ *   as  methods with the `$` prefix. This allows you to easily perform CRUD operations (create,
+ *   read, update, delete) on server-side data like this:
+ *   ```js
+ *   var User = $resource('/user/:userId', {userId:'@id'});
+ *   var user = User.get({userId:123}, function() {
+ *     user.abc = true;
+ *     user.$save();
+ *   });
+ *   ```
+ *
+ *   It is important to realize that invoking a $resource object method immediately returns an
+ *   empty reference (object or array depending on `isArray`). Once the data is returned from the
+ *   server the existing reference is populated with the actual data. This is a useful trick since
+ *   usually the resource is assigned to a model which is then rendered by the view. Having an empty
+ *   object results in no rendering, once the data arrives from the server then the object is
+ *   populated with the data and the view automatically re-renders itself showing the new data. This
+ *   means that in most cases one never has to write a callback function for the action methods.
+ *
+ *   The action methods on the class object or instance object can be invoked with the following
+ *   parameters:
+ *
+ *   - HTTP GET "class" actions: `Resource.action([parameters], [success], [error])`
+ *   - non-GET "class" actions: `Resource.action([parameters], postData, [success], [error])`
+ *   - non-GET instance actions:  `instance.$action([parameters], [success], [error])`
+ *
+ *
+ *   Success callback is called with (value, responseHeaders) arguments, where the value is
+ *   the populated resource instance or collection object. The error callback is called
+ *   with (httpResponse) argument.
+ *
+ *   Class actions return empty instance (with additional properties below).
+ *   Instance actions return promise of the action.
+ *
+ *   The Resource instances and collections have these additional properties:
+ *
+ *   - `$promise`: the {@link ng.$q promise} of the original server interaction that created this
+ *     instance or collection.
+ *
+ *     On success, the promise is resolved with the same resource instance or collection object,
+ *     updated with data from server. This makes it easy to use in
+ *     {@link ngRoute.$routeProvider resolve section of $routeProvider.when()} to defer view
+ *     rendering until the resource(s) are loaded.
+ *
+ *     On failure, the promise is rejected with the {@link ng.$http http response} object, without
+ *     the `resource` property.
+ *
+ *     If an interceptor object was provided, the promise will instead be resolved with the value
+ *     returned by the interceptor.
+ *
+ *   - `$resolved`: `true` after first server interaction is completed (either with success or
+ *      rejection), `false` before that. Knowing if the Resource has been resolved is useful in
+ *      data-binding.
+ *
+ *   The Resource instances and collections have these additional methods:
+ *
+ *   - `$cancelRequest`: If there is a cancellable, pending request related to the instance or
+ *      collection, calling this method will abort the request.
+ *
+ *   The Resource instances have these additional methods:
+ *
+ *   - `toJSON`: It returns a simple object without any of the extra properties added as part of
+ *     the Resource API. This object can be serialized through {@link angular.toJson} safely
+ *     without attaching Angular-specific fields. Notice that `JSON.stringify` (and
+ *     `angular.toJson`) automatically use this method when serializing a Resource instance
+ *     (see [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/stringify#toJSON()_behavior)).
+ *
+ * @example
+ *
+ * # Credit card resource
+ *
+ * ```js
+     // Define CreditCard class
+     var CreditCard = $resource('/user/:userId/card/:cardId',
+      {userId:123, cardId:'@id'}, {
+       charge: {method:'POST', params:{charge:true}}
+      });
+
+     // We can retrieve a collection from the server
+     var cards = CreditCard.query(function() {
+       // GET: /user/123/card
+       // server returns: [ {id:456, number:'1234', name:'Smith'} ];
+
+       var card = cards[0];
+       // each item is an instance of CreditCard
+       expect(card instanceof CreditCard).toEqual(true);
+       card.name = "J. Smith";
+       // non GET methods are mapped onto the instances
+       card.$save();
+       // POST: /user/123/card/456 {id:456, number:'1234', name:'J. Smith'}
+       // server returns: {id:456, number:'1234', name: 'J. Smith'};
+
+       // our custom method is mapped as well.
+       card.$charge({amount:9.99});
+       // POST: /user/123/card/456?amount=9.99&charge=true {id:456, number:'1234', name:'J. Smith'}
+     });
+
+     // we can create an instance as well
+     var newCard = new CreditCard({number:'0123'});
+     newCard.name = "Mike Smith";
+     newCard.$save();
+     // POST: /user/123/card {number:'0123', name:'Mike Smith'}
+     // server returns: {id:789, number:'0123', name: 'Mike Smith'};
+     expect(newCard.id).toEqual(789);
+ * ```
+ *
+ * The object returned from this function execution is a resource "class" which has "static" method
+ * for each action in the definition.
+ *
+ * Calling these methods invoke `$http` on the `url` template with the given `method`, `params` and
+ * `headers`.
+ *
+ * @example
+ *
+ * # User resource
+ *
+ * When the data is returned from the server then the object is an instance of the resource type and
+ * all of the non-GET methods are available with `$` prefix. This allows you to easily support CRUD
+ * operations (create, read, update, delete) on server-side data.

+     var User = $resource('/user/:userId', {userId:'@id'});
+     User.get({userId:123}, function(user) {
+       user.abc = true;
+       user.$save();
+     });
+   ```
+ *
+ * It's worth noting that the success callback for `get`, `query` and other methods gets passed
+ * in the response that came from the server as well as $http header getter function, so one
+ * could rewrite the above example and get access to http headers as:
+ *
+   ```js
+     var User = $resource('/user/:userId', {userId:'@id'});
+     User.get({userId:123}, function(user, getResponseHeaders){
+       user.abc = true;
+       user.$save(function(user, putResponseHeaders) {
+         //user => saved user object
+         //putResponseHeaders => $http header getter
+       });
+     });
+   ```
+ *
+ * You can also access the raw `$http` promise via the `$promise` property on the object returned
+ *
+   ```
+     var User = $resource('/user/:userId', {userId:'@id'});
+     User.get({userId:123})
+         .$promise.then(function(user) {
+           $scope.user = user;
+         });
+   ```
+ *
+ * @example
+ *
+ * # Creating a custom 'PUT' request
+ *
+ * In this example we create a custom method on our resource to make a PUT request
+ * ```js
+ *    var app = angular.module('app', ['ngResource', 'ngRoute']);
+ *
+ *    // Some APIs expect a PUT request in the format URL/object/ID
+ *    // Here we are creating an 'update' method
+ *    app.factory('Notes', ['$resource', function($resource) {
+ *    return $resource('/notes/:id', null,
+ *        {
+ *            'update': { method:'PUT' }
+ *        });
+ *    }]);
+ *
+ *    // In our controller we get the ID from the URL using ngRoute and $routeParams
+ *    // We pass in $routeParams and our Notes factory along with $scope
+ *    app.controller('NotesCtrl', ['$scope', '$routeParams', 'Notes',
+                                      function($scope, $routeParams, Notes) {
+ *    // First get a note object from the factory
+ *    var note = Notes.get({ id:$routeParams.id });
+ *    $id = note.id;
+ *
+ *    // Now call update passing in the ID first then the object you are updating
+ *    Notes.update({ id:$id }, note);
+ *
+ *    // This will PUT /notes/ID with the note object in the request payload
+ *    }]);
+ * ```
+ *
+ * @example
+ *
+ * # Cancelling requests
+ *
+ * If an action's configuration specifies that it is cancellable, you can cancel the request related
+ * to an instance or collection (as long as it is a result of a "non-instance" call):
+ *
+   ```js
+     // ...defining the `Hotel` resource...
+     var Hotel = $resource('/api/hotel/:id', {id: '@id'}, {
+       // Let's make the `query()` method cancellable
+       query: {method: 'get', isArray: true, cancellable: true}
+     });
+
+     // ...somewhere in the PlanVacationController...
+     ...
+     this.onDestinationChanged = function onDestinationChanged(destination) {
+       // We don't care about any pending request for hotels
+       // in a different destination any more
+       this.availableHotels.$cancelRequest();
+
+       // Let's query for hotels in '<destination>'
+       // (calls: /api/hotel?location=<destination>)
+       this.availableHotels = Hotel.query({location: destination});
+     };
+   ```

+
+    /**
+     * @ngdoc property
+     * @name $resourceProvider#defaults
+     * @description
+     * Object containing default options used when creating `$resource` instances.
+     *
+     * The default values satisfy a wide range of usecases, but you may choose to overwrite any of
+     * them to further customize your instances. The available properties are:
+     *
+     * - **stripTrailingSlashes** – `{boolean}` – If true, then the trailing slashes from any
+     *   calculated URL will be stripped.<br />
+     *   (Defaults to true.)
+     * - **cancellable** – `{boolean}` – If true, the request made by a "non-instance" call will be
+     *   cancelled (if not already completed) by calling `$cancelRequest()` on the call's return
+     *   value. For more details, see {@link ngResource.$resource}. This can be overwritten per
+     *   resource class or action.<br />
+     *   (Defaults to false.)
+     * - **actions** - `{Object.<Object>}` - A hash with default actions declarations. Actions are
+     *   high-level methods corresponding to RESTful actions/methods on resources. An action may
+     *   specify what HTTP method to use, what URL to hit, if the return value will be a single
+     *   object or a collection (array) of objects etc. For more details, see
+     *   {@link ngResource.$resource}. The actions can also be enhanced or overwritten per resource
+     *   class.<br />
+     *   The default actions are:
+     *   ```js
+     *   {
+     *     get: {method: 'GET'},
+     *     save: {method: 'POST'},
+     *     query: {method: 'GET', isArray: true},
+     *     remove: {method: 'DELETE'},
+     *     delete: {method: 'DELETE'}
+     *   }
+     *   ```
+     *
+     * #### Example
+     *
+     * For example, you can specify a new `update` action that uses the `PUT` HTTP verb:
+     *
+     * ```js
+     *   angular.
+     *     module('myApp').
+     *     config(['resourceProvider', function ($resourceProvider) {
+     *       $resourceProvider.defaults.actions.update = {
+     *         method: 'PUT'
+     *       };
+     *     });
+     * ```
+     *
+     * Or you can even overwrite the whole `actions` list and specify your own:
+     *
+     * ```js
+     *   angular.
+     *     module('myApp').
+     *     config(['resourceProvider', function ($resourceProvider) {
+     *       $resourceProvider.defaults.actions = {
+     *         create: {method: 'POST'}
+     *         get:    {method: 'GET'},
+     *         getAll: {method: 'GET', isArray:true},
+     *         update: {method: 'PUT'},
+     *         delete: {method: 'DELETE'}
+     *       };
+     *     });
+     * ```

+   * @name ui.router.util.$resolve#resolve
+   * @methodOf ui.router.util.$resolve
+   *
+   * @description
+   * Resolves a set of invocables. An invocable is a function to be invoked via 
+   * `$injector.invoke()`, and can have an arbitrary number of dependencies. 
+   * An invocable can either return a value directly,
+   * or a `$q` promise. If a promise is returned it will be resolved and the 
+   * resulting value will be used instead. Dependencies of invocables are resolved 
+   * (in this order of precedence)
+   *
+   * - from the specified `locals`
+   * - from another invocable that is part of this `$resolve` call
+   * - from an invocable that is inherited from a `parent` call to `$resolve` 
+   *   (or recursively
+   * - from any ancestor `$resolve` of that parent).
+   *
+   * The return value of `$resolve` is a promise for an object that contains 
+   * (in this order of precedence)
+   *
+   * - any `locals` (if specified)
+   * - the resolved return values of all injectables
+   * - any values inherited from a `parent` call to `$resolve` (if specified)
+   *
+   * The promise will resolve after the `parent` promise (if any) and all promises 
+   * returned by injectables have been resolved. If any invocable 
+   * (or `$injector.invoke`) throws an exception, or if a promise returned by an 
+   * invocable is rejected, the `$resolve` promise is immediately rejected with the 
+   * same error. A rejection of a `parent` promise (if specified) will likewise be 
+   * propagated immediately. Once the `$resolve` promise has been rejected, no 
+   * further invocables will be called.
+   * 
+   * Cyclic dependencies between invocables are not permitted and will cause `$resolve`
+   * to throw an error. As a special case, an injectable can depend on a parameter 
+   * with the same name as the injectable, which will be fulfilled from the `parent` 
+   * injectable of the same name. This allows inherited values to be decorated. 
+   * Note that in this case any other injectable in the same `$resolve` with the same
+   * dependency would see the decorated value, not the inherited value.
+   *
+   * Note that missing dependencies -- unlike cyclic dependencies -- will cause an 
+   * (asynchronous) rejection of the `$resolve` promise rather than a (synchronous) 
+   * exception.
+   *
+   * Invocables are invoked eagerly as soon as all dependencies are available. 
+   * This is true even for dependencies inherited from a `parent` call to `$resolve`.
+   *
+   * As a special case, an invocable can be a string, in which case it is taken to 
+   * be a service name to be passed to `$injector.get()`. This is supported primarily 
+   * for backwards-compatibility with the `resolve` property of `$routeProvider` 
+   * routes.
+   *
+   * @param {object} invocables functions to invoke or 
+   * `$injector` services to fetch.
+   * @param {object} locals  values to make available to the injectables
+   * @param {object} parent  a promise returned by another call to `$resolve`.
+   * @param {object} self  the `this` for the invoked methods
+   * @return {object} Promise for an object that contains the resolved return value
+   * of all invocables, as well as any inherited and local values.

+ * of search parameters. Multiple search parameter names are separated by '&'. Search parameters
+ * do not influence whether or not a URL is matched, but their values are passed through into
+ * the matched parameters returned by {@link ui.router.util.type:UrlMatcher#methods_exec exec}.
+ *
+ * Path parameter placeholders can be specified using simple colon/catch-all syntax or curly brace
+ * syntax, which optionally allows a regular expression for the parameter to be specified:
+ *
+ * * `':'` name - colon placeholder
+ * * `'*'` name - catch-all placeholder
+ * * `'{' name '}'` - curly placeholder
+ * * `'{' name ':' regexp|type '}'` - curly placeholder with regexp or type name. Should the
+ *   regexp itself contain curly braces, they must be in matched pairs or escaped with a backslash.
+ *
+ * Parameter names may contain only word characters (latin letters, digits, and underscore) and
+ * must be unique within the pattern (across both path and search parameters). For colon
+ * placeholders or curly placeholders without an explicit regexp, a path parameter matches any
+ * number of characters other than '/'. For catch-all placeholders the path parameter matches
+ * any number of characters.
+ *
+ * Examples:
+ *
+ * * `'/hello/'` - Matches only if the path is exactly '/hello/'. There is no special treatment for
+ *   trailing slashes, and patterns have to match the entire path, not just a prefix.
+ * * `'/user/:id'` - Matches '/user/bob' or '/user/1234!!!' or even '/user/' but not '/user' or

+   * <pre>

+   *     // in the list
+   *     return list.indexOf(item) > -1;
+   *   }
+   * });
+   *
+   * $stateProvider.state('list', {
+   *   url: "/list/{item:listItem}",
+   *   controller: function($scope, $stateParams) {
+   *     console.log($stateParams.item);
+   *   }

+   * // ...
+   *
+   * // Changes URL to '/list/3', logs "Ringo" to the console
+   * $state.go('list', { item: "Ringo" });
+   * </pre>
+   *
+   * This is a more complex example of a type that relies on dependency injection to
+   * interact with services, and uses the parameter name from the URL to infer how to
+   * handle encoding and decoding parameter values:
+   *
+   * <pre>
+   * // Defines a custom type that gets a value from a service,
+   * // where each service gets different types of values from
+   * // a backend API:

+   *
+   *   // Matches up services to URL parameter names
+   *   var services = {
+   *     user: Users,
+   *     post: Posts
+   *   };
+   *
+   *   return {
+   *     encode: function(object) {
+   *       // Represent the object in the URL using its unique ID
+   *       return object.id;
+   *     },
+   *     decode: function(value, key) {
+   *       // Look up the object by ID, using the parameter
+   *       // name (key) to call the correct service
+   *       return services[key].findById(value);
+   *     },
+   *     is: function(object, key) {
+   *       // Check that object is a valid dbObject
+   *       return angular.isObject(object) && object.id && services[key];
+   *     }
+   *     equals: function(a, b) {
+   *       // Check the equality of decoded objects by comparing
+   *       // their unique IDs
+   *       return a.id === b.id;
+   *     }
+   *   };
+   * });
+   *
+   * // In a config() block, you can then attach URLs with

+   * @ngdoc function
+   * @name ui.router.state.$stateProvider#decorator
+   * @methodOf ui.router.state.$stateProvider
+   *
+   * @description
+   * Allows you to extend (carefully) or override (at your own peril) the 
+   * `stateBuilder` object used internally by `$stateProvider`. This can be used 
+   * to add custom functionality to ui-router, for example inferring templateUrl 
+   * based on the state name.
+   *
+   * When passing only a name, it returns the current (original or decorated) builder
+   * function that matches `name`.
+   *
+   * The builder functions that can be decorated are listed below. Though not all
+   * necessarily have a good use case for decoration, that is up to you to decide.
+   *
+   * In addition, users can attach custom decorators, which will generate new 
+   * properties within the state's internal definition. There is currently no clear 
+   * use-case for this beyond accessing internal states (i.e. $state.$current), 
+   * however, expect this to become increasingly relevant as we introduce additional 
+   * meta-programming features.
+   *
+   * **Warning**: Decorators should not be interdependent because the order of 
+   * execution of the builder functions in non-deterministic. Builder functions 
+   * should only be dependent on the state definition object and super function.
+   *
+   *
+   * Existing builder functions and current return values:
+   *
+   * - **parent** `{object}` - returns the parent state object.
+   * - **data** `{object}` - returns state data, including any inherited data that is not
+   *   overridden by own values (if any).
+   * - **url** `{object}` - returns a {@link ui.router.util.type:UrlMatcher UrlMatcher}
+   *   or `null`.
+   * - **navigable** `{object}` - returns closest ancestor state that has a URL (aka is 
+   *   navigable).
+   * - **params** `{object}` - returns an array of state params that are ensured to 
+   *   be a super-set of parent's params.
+   * - **views** `{object}` - returns a views object where each key is an absolute view 
+   *   name (i.e. "viewName@stateName") and each value is the config object 
+   *   (template, controller) for the view. Even when you don't use the views object 
+   *   explicitly on a state config, one is still created for you internally.
+   *   So by decorating this builder function you have access to decorating template 
+   *   and controller properties.
+   * - **ownParams** `{object}` - returns an array of params that belong to the state, 
+   *   not including any params defined by ancestor states.
+   * - **path** `{string}` - returns the full path from the root down to this state. 
+   *   Needed for state activation.
+   * - **includes** `{object}` - returns an object that includes every state that 
+   *   would pass a `$state.includes()` test.
+   *
+   * @example

+   *     result[name] = config;
+   *   });
+   *   return result;

+   *   and the values of the resolved promises are injected into any controllers that reference them.
+   *   If any  of the promises are rejected the $stateChangeError event is fired.
+   *
+   *   The map object is:

+   * </pre>
+   *
+   * @param {object=} stateConfig.views
+   * <a id='views'></a>
+   * an optional map&lt;string, object&gt; which defined multiple views, or targets views
+   * manually/explicitly.
+   *
+   * Examples:
+   *
+   * Targets three named `ui-view`s in the parent state's template
+   * <pre>views: {
+   *     header: {
+   *       controller: "headerCtrl",

+   *       controller: "footCtrl",
+   *       templateUrl: "footer.html"
+   *     }
+   *   }</pre>
+   *
+   * Targets named `ui-view="header"` from grandparent state 'top''s template, and named `ui-view="body" from parent state's template.
+   * <pre>views: {
+   *     'header@top': {
+   *       controller: "msgHeaderCtrl",
+   *       templateUrl: "msgHeader.html"
+   *     }, 'body': {
+   *       controller: "messagesCtrl",
+   *       templateUrl: "messages.html"
+   *     }
+   *   }</pre>
+   *
+   * @param {boolean=} [stateConfig.abstract=false]
+   * <a id='abstract'></a>
+   * An abstract state will never be directly activated,
+   *   but can provide inherited properties to its common children states.
+   * <pre>abstract: true</pre>
+   *
+   * @param {function=} stateConfig.onEnter
+   * <a id='onEnter'></a>
+   *
+   * Callback function for when a state is entered. Good way
+   *   to trigger an action or dispatch an event, such as opening a dialog.
+   * If minifying your scripts, make sure to explicitly annotate this function,
+   * because it won't be automatically annotated by your build tools.
+   *
+   * <pre>onEnter: function(MyService, $stateParams) {
+   *     MyService.foo($stateParams.myParam);
+   * }</pre>
+   *
+   * @param {function=} stateConfig.onExit
+   * <a id='onExit'></a>
+   *
+   * Callback function for when a state is exited. Good way to
+   *   trigger an action or dispatch an event, such as opening a dialog.
+   * If minifying your scripts, make sure to explicitly annotate this function,
+   * because it won't be automatically annotated by your build tools.
+   *
+   * <pre>onExit: function(MyService, $stateParams) {
+   *     MyService.cleanup($stateParams.myParam);
+   * }</pre>
+   *
+   * @param {boolean=} [stateConfig.reloadOnSearch=true]
+   * <a id='reloadOnSearch'></a>
+   *
+   * If `false`, will not retrigger the same state
+   *   just because a search/query parameter has changed (via $location.search() or $location.hash()). 
+   *   Useful for when you'd like to modify $location.search() without triggering a reload.
+   * <pre>reloadOnSearch: false</pre>
+   *
+   * @param {object=} stateConfig.data
+   * <a id='data'></a>
+   *
+   * Arbitrary data object, useful for custom configuration.  The parent state's `data` is
+   *   prototypally inherited.  In other words, adding a data property to a state adds it to
+   *   the entire subtree via prototypal inheritance.
+   *
+   * <pre>data: {
+   *     requiredRole: 'foo'
+   * } </pre>
+   *
+   * @param {object=} stateConfig.params
+   * <a id='params'></a>
+   *
+   * A map which optionally configures parameters declared in the `url`, or
+   *   defines additional non-url parameters.  For each parameter being
+   *   configured, add a configuration object keyed to the name of the parameter.
+   *
+   *   Each parameter configuration object may contain the following properties:
+   *
+   *   - ** value ** - {object|function=}: specifies the default value for this
+   *     parameter.  This implicitly sets this parameter as optional.
+   *
+   *     When UI-Router routes to a state and no value is
+   *     specified for this parameter in the URL or transition, the
+   *     default value will be used instead.  If `value` is a function,
+   *     it will be injected and invoked, and the return value used.
+   *
+   *     *Note*: `undefined` is treated as "no default value" while `null`
+   *     is treated as "the default value is `null`".
+   *
+   *     *Shorthand*: If you only need to configure the default value of the
+   *     parameter, you may use a shorthand syntax.   In the **`params`**
+   *     map, instead mapping the param name to a full parameter configuration
+   *     object, simply set map it to the default parameter value, e.g.:
+   *
+   * <pre>// define a parameter's default value
+   * params: {
+   *     param1: { value: "defaultValue" }
+   * }
+   * // shorthand default values
+   * params: {
+   *     param1: "defaultValue",
+   *     param2: "param2Default"
+   * }</pre>
+   *
+   *   - ** array ** - {boolean=}: *(default: false)* If true, the param value will be
+   *     treated as an array of values.  If you specified a Type, the value will be
+   *     treated as an array of the specified Type.  Note: query parameter values
+   *     default to a special `"auto"` mode.
+   *
+   *     For query parameters in `"auto"` mode, if multiple  values for a single parameter
+   *     are present in the URL (e.g.: `/foo?bar=1&bar=2&bar=3`) then the values
+   *     are mapped to an array (e.g.: `{ foo: [ '1', '2', '3' ] }`).  However, if
+   *     only one value is present (e.g.: `/foo?bar=1`) then the value is treated as single
+   *     value (e.g.: `{ foo: '1' }`).
+   *
+   * <pre>params: {
+   *     param1: { array: true }
+   * }</pre>
+   *
+   *   - ** squash ** - {bool|string=}: `squash` configures how a default parameter value is represented in the URL when
+   *     the current parameter value is the same as the default value. If `squash` is not set, it uses the
+   *     configured default squash policy.
+   *     (See {@link ui.router.util.$urlMatcherFactory#methods_defaultSquashPolicy `defaultSquashPolicy()`})
+   *
+   *   There are three squash settings:
+   *
+   *     - false: The parameter's default value is not squashed.  It is encoded and included in the URL
+   *     - true: The parameter's default value is omitted from the URL.  If the parameter is preceeded and followed
+   *       by slashes in the state's `url` declaration, then one of those slashes are omitted.
+   *       This can allow for cleaner looking URLs.
+   *     - `"<arbitrary string>"`: The parameter's default value is replaced with an arbitrary placeholder of  your choice.
+   *
+   * <pre>params: {
+   *     param1: {
+   *       value: "defaultId",
+   *       squash: true
+   * } }
+   * // squash "defaultValue" to "~"
+   * params: {
+   *     param1: {
+   *       value: "defaultValue",
+   *       squash: "~"
+   * } }
+   * </pre>
+   *
+   *
+   * @example
+   * <pre>
+   * // Some state name examples
+   *
+   * // stateName can be a single top-level name (must be unique).
+   * $stateProvider.state("home", {});

+   * $stateProvider.state("home.newest.abc.xyz.inception", {});

+     * - `$state.go('^.sibling')` - will go to a sibling state
+     * - `$state.go('.child.grandchild')` - will go to grandchild state
+     *
+     * @param {object=} params A map of the parameters that will be sent to the state, 
+     * will populate $stateParams. Any parameters that are not specified will be inherited from currently 
+     * defined parameters. Only parameters specified in the state definition can be overridden, new 
+     * parameters will be ignored. This allows, for example, going to a sibling state that shares parameters
+     * specified in a parent state. Parameter inheritance only works between common ancestor states, I.e.
+     * transitioning to a sibling will get you the parameters for all parents, transitioning to a child
+     * will get you all current parameters, etc.
+     * @param {object=} options Options object. The options are:
+     *
+     * - **`location`** - {boolean=true|string=} - If `true` will update the url in the location bar, if `false`
+     *    will not. If string, must be `"replace"`, which will update url and also replace last history record.
+     * - **`inherit`** - {boolean=true}, If `true` will inherit url parameters from current url.
+     * - **`relative`** - {object=$state.$current}, When transitioning with relative path (e.g '^'), 
+     *    defines which state to be relative from.
+     * - **`notify`** - {boolean=true}, If `true` will broadcast $stateChangeStart and $stateChangeSuccess events.
+     * - **`reload`** (v0.2.5) - {boolean=false|string|object}, If `true` will force transition even if no state or params
+     *    have changed.  It will reload the resolves and views of the current state and parent states.
+     *    If `reload` is a string (or state object), the state object is fetched (by name, or object reference); and \
+     *    the transition reloads the resolves and views for that matched state, and all its children states.
+     *
+     * @returns {promise} A promise representing the state of the new transition.
+     *
+     * Possible success values:
+     *
+     * - $state.current
+     *
+     * <br/>Possible rejection values:
+     *
+     * - 'transition superseded' - when a newer transition has been started after this one
+     * - 'transition prevented' - when `event.preventDefault()` has been called in a `$stateChangeStart` listener
+     * - 'transition aborted' - when `event.preventDefault()` has been called in a `$stateNotFound` listener or
+     *   when a `$stateNotFound` `event.retry` promise errors.

+ * <pre>
+ * <div ui-view></div>
+ * $stateProvider.state("home", {
+ *   template: "<h1>HELLO!</h1>"
+ * })
+ * </pre>
+ *
+ * The above is a convenient shortcut equivalent to specifying your view explicitly with the {@link ui.router.state.$stateProvider#methods_state `views`}
+ * config property, by name, in this case an empty name:
+ * <pre>
+ * $stateProvider.state("home", {
+ *   views: {
+ *     "": {
+ *       template: "<h1>HELLO!</h1>"
+ *     }
+ *   }    
+ * })
+ * </pre>
+ *
+ * But typically you'll only use the views property if you name your view or have more than one view
+ * in the same template. There's not really a compelling reason to name a view if its the only one,
+ * but you could if you wanted, like so:
+ * <pre>
+ * <div ui-view="main"></div>
+ * </pre>
+ * <pre>
+ * $stateProvider.state("home", {
+ *   views: {
+ *     "main": {
+ *       template: "<h1>HELLO!</h1>"
+ *     }
+ *   }    
+ * })
+ * </pre>
+ *
+ * Really though, you'll use views to set up multiple views:
+ * <pre>
+ * <div ui-view></div>
+ * <div ui-view="chart"></div>
+ * <div ui-view="data"></div>
+ * </pre>
+ *
+ * <pre>
+ * $stateProvider.state("home", {
+ *   views: {
+ *     "": {
+ *       template: "<h1>HELLO!</h1>"
+ *     },
+ *     "chart": {
+ *       template: "<chart_thing/>"
+ *     },
+ *     "data": {
+ *       template: "<data_thing/>"
+ *     }
+ *   }    
+ * })
+ * </pre>
+ *
+ * Examples for `autoscroll`:
+ *
+ * <pre>
+ * <!-- If autoscroll present with no expression,
+ *      then scroll ui-view into view -->
+ * <ui-view autoscroll/>
+ *
+ * <!-- If autoscroll present with valid expression,
+ *      then scroll ui-view into view if expression evaluates to true -->
+ * <ui-view autoscroll='true'/>
+ * <ui-view autoscroll='false'/>
+ * <ui-view autoscroll='scopeVariable'/>
+ * </pre>
+ *
+ * Resolve data:
+ *
+ * The resolved data from the state's `resolve` block is placed on the scope as `$resolve` (this
+ * can be customized using [[ViewDeclaration.resolveAs]]).  This can be then accessed from the template.
+ *
+ * Note that when `controllerAs` is being used, `$resolve` is set on the controller instance *after* the
+ * controller is instantiated.  The `$onInit()` hook can be used to perform initialization code which
+ * depends on `$resolve` data.
+ *
+ * Example usage of $resolve in a view template
+ * <pre>
+ * $stateProvider.state('home', {
+ *   template: '<my-component user="$resolve.user"></my-component>',
+ *   resolve: {
+ *     user: function(UserService) { return UserService.fetchUser(); }
+ *   }
+ * });
+ * </pre>

+ * @restrict A
+ *
+ * @description
+ * A directive that binds a link (`<a>` tag) to a state. If the state has an associated
+ * URL, the directive will automatically generate & update the `href` attribute via
+ * the {@link ui.router.state.$state#methods_href $state.href()} method. Clicking
+ * the link will trigger a state transition with optional parameters.
+ *
+ * Also middle-clicking, right-clicking, and ctrl-clicking on the link will be
+ * handled natively by the browser.
+ *
+ * You can also use relative state paths within ui-sref, just like the relative
+ * paths passed to `$state.go()`. You just need to be aware that the path is relative
+ * to the state that the link lives in, in other words the state that loaded the
+ * template containing the link.
+ *
+ * You can specify options to pass to {@link ui.router.state.$state#methods_go $state.go()}
+ * using the `ui-sref-opts` attribute. Options are restricted to `location`, `inherit`,
+ * and `reload`.
+ *
+ * @example
+ * Here's an example of how you'd use ui-sref and how it would compile. If you have the
+ * following template:
+ * <pre>
+ * <a ui-sref="home">Home</a> | <a ui-sref="about">About</a> | <a ui-sref="{page: 2}">Next page</a>
+ *
+ * <ul>
+ *     <li ng-repeat="contact in contacts">
+ *         <a ui-sref="contacts.detail({ id: contact.id })">{{ contact.name }}</a>
+ *     </li>
+ * </ul>
+ * </pre>
+ *
+ * Then the compiled html would be (assuming Html5Mode is off and current state is contacts):
+ * <pre>
+ * <a href="#/home" ui-sref="home">Home</a> | <a href="#/about" ui-sref="about">About</a> | <a href="#/contacts?page=2" ui-sref="{page: 2}">Next page</a>

+ * @description
+ * A directive working alongside ui-sref to add classes to an element when the
+ * related ui-sref directive's state is active, and removing them when it is inactive.
+ * The primary use-case is to simplify the special appearance of navigation menus
+ * relying on `ui-sref`, by having the "active" state's menu button appear different,
+ * distinguishing it from the inactive menu items.
+ *
+ * ui-sref-active can live on the same element as ui-sref or on a parent element. The first
+ * ui-sref-active found at the same level or above the ui-sref will be used.
+ *
+ * Will activate when the ui-sref's target state or any child state is active. If you
+ * need to activate only when the ui-sref target state is active and *not* any of
+ * it's children, then you will use
+ * {@link ui.router.state.directive:ui-sref-active-eq ui-sref-active-eq}
+ *
+ * @example
+ * Given the following template:
+ * <pre>
+ * <ul>
+ *   <li ui-sref-active="active" class="item">
+ *     <a href ui-sref="app.user({user: 'bilbobaggins'})">@bilbobaggins</a>
+ *   </li>
+ * </ul>
+ * </pre>
+ *
+ *
+ * When the app state is "app.user" (or any children states), and contains the state parameter "user" with value "bilbobaggins",
+ * the resulting HTML will appear as (note the 'active' class):
+ * <pre>
+ * <ul>
+ *   <li ui-sref-active="active" class="item active">
+ *     <a ui-sref="app.user({user: 'bilbobaggins'})" href="/users/bilbobaggins">@bilbobaggins</a>
+ *   </li>
+ * </ul>
+ * </pre>
+ *
+ * The class name is interpolated **once** during the directives link time (any further changes to the
+ * interpolated value are ignored).
+ *
+ * Multiple classes may be specified in a space-separated format:
+ * <pre>
+ * <ul>
+ *   <li ui-sref-active='class1 class2 class3'>
+ *     <a ui-sref="app.user">link</a>
+ *   </li>
+ * </ul>
+ * </pre>
+ *
+ * It is also possible to pass ui-sref-active an expression that evaluates
+ * to an object hash, whose keys represent active class names and whose
+ * values represent the respective state names/globs.
+ * ui-sref-active will match if the current active state **includes** any of
+ * the specified state names/globs, even the abstract ones.
+ *
+ * @Example
+ * Given the following template, with "admin" being an abstract state:
+ * <pre>
+ * <div ui-sref-active="{'active': 'admin.*'}">
+ *   <a ui-sref-active="active" ui-sref="admin.roles">Roles</a>
+ * </div>
+ * </pre>
+ *
+ * When the current state is "admin.roles" the "active" class will be applied
+ * to both the <div> and <a> elements. It is important to note that the state
+ * names/globs passed to ui-sref-active shadow the state provided by ui-sref.

+ * This object provides a utility for producing rich Error messages within
+ * Angular. It can be called as follows:
+ *
+ * var exampleMinErr = minErr('example');
+ * throw exampleMinErr('one', 'This {0} is {1}', foo, bar);
+ *
+ * The above creates an instance of minErr in the example namespace. The
+ * resulting error will have a namespaced error code of example.one.  The
+ * resulting error will replace {0} with the value of foo, and {1} with the
+ * value of bar. The object is not restricted in the number of arguments it can
+ * take.
+ *
+ * If fewer arguments are specified than necessary for interpolation, the extra
+ * interpolation markers will be preserved in the final string.
+ *
+ * Since data will be parsed statically during a build step, some restrictions
+ * are applied with respect to how minErr instances are created and called.
+ * Instances should have names of the form namespaceMinErr for a minErr created
+ * using minErr('namespace') . Error codes, namespaces and template strings
+ * should all be static strings, not variables or general expressions.
+ *
+ * @param {string} module The namespace to use for the new minErr instance.
+ * @param {function} ErrorConstructor Custom error constructor to be instantiated when returning
+ *   error from returned function, for cases when a particular type of error is useful.
+ * @returns {function(code:string, template:string, ...templateArgs): Error} minErr instance

+ * @ngdoc directive

+ *
+ * @element ANY
+ * @param {angular.Module} ngApp an optional application
+ *   {@link angular.module module} name to load.
+ * @param {boolean=} ngStrictDi if this attribute is present on the app element, the injector will be
+ *   created in "strict-di" mode. This means that the application will fail to invoke functions which
+ *   do not use explicit function annotation (and are thus unsuitable for minification), as described
+ *   in {@link guide/di the Dependency Injection guide}, and useful debugging info will assist in
+ *   tracking down the root of these bugs.
+ *
+ * @description
+ *
+ * Use this directive to **auto-bootstrap** an AngularJS application. The `ngApp` directive
+ * designates the **root element** of the application and is typically placed near the root element
+ * of the page - e.g. on the `<body>` or `<html>` tags.
+ *
+ * There are a few things to keep in mind when using `ngApp`:
+ * - only one AngularJS application can be auto-bootstrapped per HTML document. The first `ngApp`
+ *   found in the document will be used to define the root element to auto-bootstrap as an
+ *   application. To run multiple applications in an HTML document you must manually bootstrap them using
+ *   {@link angular.bootstrap} instead.
+ * - AngularJS applications cannot be nested within each other.
+ * - Do not use a directive that uses {@link ng.$compile#transclusion transclusion} on the same element as `ngApp`.
+ *   This includes directives such as {@link ng.ngIf `ngIf`}, {@link ng.ngInclude `ngInclude`} and
+ *   {@link ngRoute.ngView `ngView`}.
+ *   Doing this misplaces the app {@link ng.$rootElement `$rootElement`} and the app's {@link auto.$injector injector},
+ *   causing animations to stop working and making the injector inaccessible from outside the app.
+ *
+ * You can specify an **AngularJS module** to be used as the root module for the application.  This
+ * module will be loaded into the {@link auto.$injector} when the application is bootstrapped. It
+ * should contain the application code needed or have dependencies on other modules that will
+ * contain the code. See {@link angular.module} for more information.
+ *
+ * In the example below if the `ngApp` directive were not placed on the `html` element then the
+ * document would not be compiled, the `AppController` would not be instantiated and the `{{ a+b }}`
+ * would not be resolved to `3`.
+ *
+ * `ngApp` is the easiest, and most common way to bootstrap an application.
+ *
+ <example module="ngAppDemo">
+   <file name="index.html">
+   <div ng-controller="ngAppDemoController">
+     I can add: {{a}} + {{b}} =  {{ a+b }}

+     $scope.a = 1;
+     $scope.b = 2;
+   });
+   </file>
+ </example>
+ *
+ * Using `ngStrictDi`, you would see something like this:
+ *
+ <example ng-app-included="true">
+   <file name="index.html">
+   <div ng-app="ngAppStrictDemo" ng-strict-di>
+       <div ng-controller="GoodController1">
+           I can add: {{a}} + {{b}} =  {{ a+b }}

+     * The `angular.module` is a global place for creating, registering and retrieving Angular
+     * modules.
+     * All modules (angular core or 3rd party) that should be available to an application must be
+     * registered using this mechanism.
+     *

+     *
+     *
+     * # Module
+     *
+     * A module is a collection of services, directives, controllers, filters, and configuration information.
+     * `angular.module` is used to configure the {@link auto.$injector $injector}.
+     *
+     * ```js
+     * // Create a new module
+     * var myModule = angular.module('myModule', []);
+     *
+     * // register a new service
+     * myModule.value('appName', 'MyCoolApp');
+     *
+     * // configure existing services inside initialization blocks.
+     * myModule.config(['$locationProvider', function($locationProvider) {
+     *   // Configure existing providers
+     *   $locationProvider.hashPrefix('!');
+     * }]);
+     * ```
+     *
+     * Then you can create an injector and load your modules like this:
+     *
+     * ```js
+     * var injector = angular.injector(['ng', 'myModule'])
+     * ```
+     *
+     * However it's more likely that you'll just use
+     * {@link ng.directive:ngApp ngApp} or
+     * {@link angular.bootstrap} to simplify this process for you.
+     *
+     * @param {!string} name The name of the module to create or retrieve.
+     * @param {!Array.<string>=} requires If specified then new module is being created. If
+     *        unspecified then the module is being retrieved for further configuration.
+     * @param {Function=} configFn Optional configuration function for the module. Same as
+     *        {@link angular.Module#config Module#config()}.
+     * @returns {angular.Module} new module with the {@link angular.Module} api.

+/**
+ * @ngdoc function
+ * @name angular.element
+ * @module ng
+ * @kind function
+ *
+ * @description
+ * Wraps a raw DOM element or HTML string as a [jQuery](http://jquery.com) element.
+ *
+ * If jQuery is available, `angular.element` is an alias for the
+ * [jQuery](http://api.jquery.com/jQuery/) function. If jQuery is not available, `angular.element`
+ * delegates to Angular's built-in subset of jQuery, called "jQuery lite" or **jqLite**.
+ *
+ * jqLite is a tiny, API-compatible subset of jQuery that allows
+ * Angular to manipulate the DOM in a cross-browser compatible way. jqLite implements only the most
+ * commonly needed functionality with the goal of having a very small footprint.
+ *
+ * To use `jQuery`, simply ensure it is loaded before the `angular.js` file. You can also use the
+ * {@link ngJq `ngJq`} directive to specify that jqlite should be used over jQuery, or to use a
+ * specific version of jQuery if multiple versions exist on the page.
+ *
+ * <div class="alert alert-info">**Note:** All element references in Angular are always wrapped with jQuery or
+ * jqLite (such as the element argument in a directive's compile / link function). They are never raw DOM references.</div>
+ *
+ * <div class="alert alert-warning">**Note:** Keep in mind that this function will not find elements
+ * by tag name / CSS selector. For lookups by tag name, try instead `angular.element(document).find(...)`
+ * or `$document.find()`, or use the standard DOM APIs, e.g. `document.querySelectorAll()`.</div>
+ *
+ * ## Angular's jqLite
+ * jqLite provides only the following jQuery methods:
+ *
+ * - [`addClass()`](http://api.jquery.com/addClass/) - Does not support a function as first argument
+ * - [`after()`](http://api.jquery.com/after/)
+ * - [`append()`](http://api.jquery.com/append/)
+ * - [`attr()`](http://api.jquery.com/attr/) - Does not support functions as parameters
+ * - [`bind()`](http://api.jquery.com/bind/) - Does not support namespaces, selectors or eventData
+ * - [`children()`](http://api.jquery.com/children/) - Does not support selectors
+ * - [`clone()`](http://api.jquery.com/clone/)
+ * - [`contents()`](http://api.jquery.com/contents/)
+ * - [`css()`](http://api.jquery.com/css/) - Only retrieves inline-styles, does not call `getComputedStyle()`.
+ *   As a setter, does not convert numbers to strings or append 'px', and also does not have automatic property prefixing.
+ * - [`data()`](http://api.jquery.com/data/)
+ * - [`detach()`](http://api.jquery.com/detach/)
+ * - [`empty()`](http://api.jquery.com/empty/)
+ * - [`eq()`](http://api.jquery.com/eq/)
+ * - [`find()`](http://api.jquery.com/find/) - Limited to lookups by tag name
+ * - [`hasClass()`](http://api.jquery.com/hasClass/)
+ * - [`html()`](http://api.jquery.com/html/)
+ * - [`next()`](http://api.jquery.com/next/) - Does not support selectors
+ * - [`on()`](http://api.jquery.com/on/) - Does not support namespaces, selectors or eventData
+ * - [`off()`](http://api.jquery.com/off/) - Does not support namespaces, selectors or event object as parameter
+ * - [`one()`](http://api.jquery.com/one/) - Does not support namespaces or selectors
+ * - [`parent()`](http://api.jquery.com/parent/) - Does not support selectors
+ * - [`prepend()`](http://api.jquery.com/prepend/)
+ * - [`prop()`](http://api.jquery.com/prop/)
+ * - [`ready()`](http://api.jquery.com/ready/)
+ * - [`remove()`](http://api.jquery.com/remove/)
+ * - [`removeAttr()`](http://api.jquery.com/removeAttr/)
+ * - [`removeClass()`](http://api.jquery.com/removeClass/) - Does not support a function as first argument
+ * - [`removeData()`](http://api.jquery.com/removeData/)
+ * - [`replaceWith()`](http://api.jquery.com/replaceWith/)
+ * - [`text()`](http://api.jquery.com/text/)
+ * - [`toggleClass()`](http://api.jquery.com/toggleClass/) - Does not support a function as first argument
+ * - [`triggerHandler()`](http://api.jquery.com/triggerHandler/) - Passes a dummy event object to handlers
+ * - [`unbind()`](http://api.jquery.com/unbind/) - Does not support namespaces or event object as parameter
+ * - [`val()`](http://api.jquery.com/val/)
+ * - [`wrap()`](http://api.jquery.com/wrap/)
+ *
+ * ## jQuery/jqLite Extras
+ * Angular also provides the following additional methods and events to both jQuery and jqLite:
+ *
+ * ### Events
+ * - `$destroy` - AngularJS intercepts all jqLite/jQuery's DOM destruction apis and fires this event
+ *    on all DOM nodes being removed.  This can be used to clean up any 3rd party bindings to the DOM
+ *    element before it is removed.
+ *
+ * ### Methods
+ * - `controller(name)` - retrieves the controller of the current element or its parent. By default
+ *   retrieves controller associated with the `ngController` directive. If `name` is provided as
+ *   camelCase directive name, then the controller for this directive will be retrieved (e.g.
+ *   `'ngModel'`).
+ * - `injector()` - retrieves the injector of the current element or its parent.
+ * - `scope()` - retrieves the {@link ng.$rootScope.Scope scope} of the current
+ *   element or its parent. Requires {@link guide/production#disabling-debug-data Debug Data} to
+ *   be enabled.
+ * - `isolateScope()` - retrieves an isolate {@link ng.$rootScope.Scope scope} if one is attached directly to the
+ *   current element. This getter should be used only on elements that contain a directive which starts a new isolate
+ *   scope. Calling `scope()` on this element always returns the original non-isolate scope.
+ *   Requires {@link guide/production#disabling-debug-data Debug Data} to be enabled.
+ * - `inheritedData()` - same as `data()`, but walks up the DOM until a value is found or the top
+ *   parent element is reached.
+ *
+ * @knownIssue You cannot spy on `angular.element` if you are using Jasmine version 1.x. See
+ * https://github.com/angular/angular.js/issues/14251 for more information.
+ *
+ * @param {string|DOMElement} element HTML string or DOMElement to be wrapped into jQuery.
+ * @returns {Object} jQuery object.

+ *
+ * # Injection Function Annotation
+ *
+ * JavaScript does not have annotations, and annotations are needed for dependency injection. The
+ * following are all valid ways of annotating function with injection arguments and are equivalent.
+ *
+ * ```js
+ *   // inferred (only works if code not minified/obfuscated)
+ *   $injector.invoke(function(serviceA){});
+ *
+ *   // annotated
+ *   function explicit(serviceA) {};

+ *   // inline
+ *   $injector.invoke(['serviceA', function(serviceA){}]);
+ * ```
+ *
+ * ## Inference
+ *
+ * In JavaScript calling `toString()` on a function returns the function definition. The definition
+ * can then be parsed and the function arguments can be extracted. This method of discovering
+ * annotations is disallowed when the injector is in strict mode.
+ * *NOTE:* This does not work with minification, and obfuscation tools since these tools change the
+ * argument names.
+ *
+ * ## `$inject` Annotation
+ * By adding an `$inject` property onto a function the injection parameters can be specified.

+ *
+ * @description
+ * Returns an array of service names which the function is requesting for injection. This API is
+ * used by the injector to determine which services need to be injected into the function when the
+ * function is invoked. There are three ways in which the function can be annotated with the needed
+ * dependencies.
+ *
+ * # Argument names
+ *
+ * The simplest form is to extract the dependencies from the arguments of the function. This is done
+ * by converting the function into a string using `toString()` method and extracting the argument
+ * names.
+ * ```js
+ *   // Given
+ *   function MyController($scope, $route) {
+ *     // ...
+ *   }
+ *
+ *   // Then
+ *   expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
+ * ```
+ *
+ * You can disallow this method by using strict injection mode.
+ *
+ * This method does not work with code minification / obfuscation. For this reason the following
+ * annotation strategies are supported.
+ *
+ * # The `$inject` property
+ *
+ * If a function has an `$inject` property and its value is an array of strings, then the strings
+ * represent names of services to be injected into the function.
+ * ```js
+ *   // Given
+ *   var MyController = function(obfuscatedScope, obfuscatedRoute) {
+ *     // ...
+ *   }
+ *   // Define function dependencies
+ *   MyController['$inject'] = ['$scope', '$route'];
+ *
+ *   // Then
+ *   expect(injector.annotate(MyController)).toEqual(['$scope', '$route']);
+ * ```
+ *
+ * # The array notation
+ *
+ * It is often desirable to inline Injected functions and that's when setting the `$inject` property
+ * is very inconvenient. In these situations using the array notation to specify the dependencies in
+ * a way that survives minification is a better choice:
+ *
+ * ```js
+ *   // We wish to write this (not minification / obfuscation safe)
+ *   injector.invoke(function($compile, $rootScope) {
+ *     // ...
+ *   });
+ *
+ *   // We are forced to write break inlining
+ *   var tmpFn = function(obfuscatedCompile, obfuscatedRootScope) {
+ *     // ...
+ *   };
+ *   tmpFn.$inject = ['$compile', '$rootScope'];
+ *   injector.invoke(tmpFn);
+ *
+ *   // To better support inline function the inline annotation is supported
+ *   injector.invoke(['$compile', '$rootScope', function(obfCompile, obfRootScope) {
+ *     // ...
+ *   }]);
+ *
+ *   // Therefore
+ *   expect(injector.annotate(
+ *      ['$compile', '$rootScope', function(obfus_$compile, obfus_$rootScope) {}])
+ *    ).toEqual(['$compile', '$rootScope']);

+ * When you request a service, the {@link auto.$injector $injector} is responsible for finding the

+ * Register a **provider function** with the {@link auto.$injector $injector}. Provider functions

+ *
+ * Service provider names start with the name of the service they provide followed by `Provider`.
+ * For example, the {@link ng.$log $log} service has a provider called
+ * {@link ng.$logProvider $logProvider}.
+ *
+ * Service provider objects can have additional methods which allow configuration of the provider
+ * and its service. Importantly, you can configure what kind of service is created by the `$get`
+ * method, or how that service will act. For example, the {@link ng.$logProvider $logProvider} has a
+ * method {@link ng.$logProvider#debugEnabled debugEnabled}
+ * which lets you specify whether the {@link ng.$log $log} service will log debug messages to the
+ * console or not.
+ *
+ * @param {string} name The name of the instance. NOTE: the provider will be available under `name +
+                        'Provider'` key.
+ * @param {(Object|function())} provider If the provider is:
+ *
+ *   - `Object`: then it should have a `$get` method. The `$get` method will be invoked using
+ *     {@link auto.$injector#invoke $injector.invoke()} when an instance needs to be created.
+ *   - `Constructor`: a new instance of the provider will be created using
+ *     {@link auto.$injector#instantiate $injector.instantiate()}, then treated as `object`.
+ *
+ * @returns {Object} registered provider instance

+ *
+ * <div class="alert alert-warning">
+ * **Note:** This document is an in-depth reference of all directive options.
+ * For a gentle introduction to directives with examples of common use cases,
+ * see the {@link guide/directive directive guide}.
+ * </div>
+ *
+ * ## Comprehensive Directive API
+ *
+ * There are many different options for a directive.
+ *
+ * The difference resides in the return value of the factory function.
+ * You can either return a {@link $compile#directive-definition-object Directive Definition Object (see below)}
+ * that defines the directive properties, or just the `postLink` function (all other properties will have
+ * the default values).
+ *
+ * <div class="alert alert-success">
+ * **Best Practice:** It's recommended to use the "directive definition object" form.
+ * </div>
+ *
+ * Here's an example directive declared with a Directive Definition Object:
+ *
+ * ```js
+ *   var myModule = angular.module(...);
+ *
+ *   myModule.directive('directiveName', function factory(injectables) {
+ *     var directiveDefinitionObject = {
+ *       priority: 0,
+ *       template: '<div></div>', // or // function(tElement, tAttrs) { ... },
+ *       // or
+ *       // templateUrl: 'directive.html', // or // function(tElement, tAttrs) { ... },
+ *       transclude: false,
+ *       restrict: 'A',
+ *       templateNamespace: 'html',
+ *       scope: false,
+ *       controller: function($scope, $element, $attrs, $transclude, otherInjectables) { ... },
+ *       controllerAs: 'stringIdentifier',
+ *       bindToController: false,
+ *       require: 'siblingDirectiveName', // or // ['^parentDirectiveName', '?optionalDirectiveName', '?^optionalParent'],
+ *       compile: function compile(tElement, tAttrs, transclude) {
+ *         return {
+ *           pre: function preLink(scope, iElement, iAttrs, controller) { ... },
+ *           post: function postLink(scope, iElement, iAttrs, controller) { ... }
+ *         }
+ *         // or
+ *         // return function postLink( ... ) { ... }
+ *       },
+ *       // or
+ *       // link: {
+ *       //  pre: function preLink(scope, iElement, iAttrs, controller) { ... },
+ *       //  post: function postLink(scope, iElement, iAttrs, controller) { ... }
+ *       // }
+ *       // or
+ *       // link: function postLink( ... ) { ... }
+ *     };
+ *     return directiveDefinitionObject;
+ *   });
+ * ```
+ *
+ * <div class="alert alert-warning">
+ * **Note:** Any unspecified options will use the default value. You can see the default values below.
+ * </div>
+ *
+ * Therefore the above can be simplified as:
+ *
+ * ```js
+ *   var myModule = angular.module(...);
+ *
+ *   myModule.directive('directiveName', function factory(injectables) {
+ *     var directiveDefinitionObject = {
+ *       link: function postLink(scope, iElement, iAttrs) { ... }
+ *     };
+ *     return directiveDefinitionObject;
+ *     // or
+ *     // return function postLink(scope, iElement, iAttrs) { ... }
+ *   });
+ * ```
+ *
+ * ### Life-cycle hooks
+ * Directive controllers can provide the following methods that are called by Angular at points in the life-cycle of the
+ * directive:
+ * * `$onInit()` - Called on each controller after all the controllers on an element have been constructed and
+ *   had their bindings initialized (and before the pre &amp; post linking functions for the directives on
+ *   this element). This is a good place to put initialization code for your controller.
+ * * `$onChanges(changesObj)` - Called whenever one-way (`<`) or interpolation (`@`) bindings are updated. The
+ *   `changesObj` is a hash whose keys are the names of the bound properties that have changed, and the values are an
+ *   object of the form `{ currentValue, previousValue, isFirstChange() }`. Use this hook to trigger updates within a
+ *   component such as cloning the bound value to prevent accidental mutation of the outer value.
+ * * `$doCheck()` - Called on each turn of the digest cycle. Provides an opportunity to detect and act on
+ *   changes. Any actions that you wish to take in response to the changes that you detect must be
+ *   invoked from this hook; implementing this has no effect on when `$onChanges` is called. For example, this hook
+ *   could be useful if you wish to perform a deep equality check, or to check a Date object, changes to which would not
+ *   be detected by Angular's change detector and thus not trigger `$onChanges`. This hook is invoked with no arguments;
+ *   if detecting changes, you must store the previous value(s) for comparison to the current values.
+ * * `$onDestroy()` - Called on a controller when its containing scope is destroyed. Use this hook for releasing
+ *   external resources, watches and event handlers. Note that components have their `$onDestroy()` hooks called in
+ *   the same order as the `$scope.$broadcast` events are triggered, which is top down. This means that parent
+ *   components will have their `$onDestroy()` hook called before child components.
+ * * `$postLink()` - Called after this controller's element and its children have been linked. Similar to the post-link
+ *   function this hook can be used to set up DOM event handlers and do direct DOM manipulation.
+ *   Note that child elements that contain `templateUrl` directives will not have been compiled and linked since
+ *   they are waiting for their template to load asynchronously and their own compilation and linking has been
+ *   suspended until that occurs.
+ *
+ * #### Comparison with Angular 2 life-cycle hooks
+ * Angular 2 also uses life-cycle hooks for its components. While the Angular 1 life-cycle hooks are similar there are
+ * some differences that you should be aware of, especially when it comes to moving your code from Angular 1 to Angular 2:
+ *
+ * * Angular 1 hooks are prefixed with `$`, such as `$onInit`. Angular 2 hooks are prefixed with `ng`, such as `ngOnInit`.
+ * * Angular 1 hooks can be defined on the controller prototype or added to the controller inside its constructor.
+ *   In Angular 2 you can only define hooks on the prototype of the Component class.
+ * * Due to the differences in change-detection, you may get many more calls to `$doCheck` in Angular 1 than you would to
+ *   `ngDoCheck` in Angular 2
+ * * Changes to the model inside `$doCheck` will trigger new turns of the digest loop, which will cause the changes to be
+ *   propagated throughout the application.
+ *   Angular 2 does not allow the `ngDoCheck` hook to trigger a change outside of the component. It will either throw an
+ *   error or do nothing depending upon the state of `enableProdMode()`.
+ *
+ * #### Life-cycle hook examples
+ *
+ * This example shows how you can check for mutations to a Date object even though the identity of the object
+ * has not changed.
+ *
+ * <example name="doCheckDateExample" module="do-check-module">
+ *   <file name="app.js">
+ *     angular.module('do-check-module', [])
+ *       .component('app', {
+ *         template:
+ *           'Month: <input ng-model="$ctrl.month" ng-change="$ctrl.updateDate()">' +
+ *           'Date: {{ $ctrl.date }}' +
+ *           '<test date="$ctrl.date"></test>',
+ *         controller: function() {
+ *           this.date = new Date();
+ *           this.month = this.date.getMonth();
+ *           this.updateDate = function() {
+ *             this.date.setMonth(this.month);
+ *           };
+ *         }
+ *       })
+ *       .component('test', {
+ *         bindings: { date: '<' },
+ *         template:
+ *           '<pre>{{ $ctrl.log | json }}</pre>',
+ *         controller: function() {
+ *           var previousValue;
+ *           this.log = [];
+ *           this.$doCheck = function() {
+ *             var currentValue = this.date && this.date.valueOf();
+ *             if (previousValue !== currentValue) {
+ *               this.log.push('doCheck: date mutated: ' + this.date);
+ *               previousValue = currentValue;
+ *             }
+ *           };
+ *         }
+ *       });
+ *   </file>
+ *   <file name="index.html">
+ *     <app></app>
+ *   </file>
+ * </example>
+ *
+ * This example show how you might use `$doCheck` to trigger changes in your component's inputs even if the
+ * actual identity of the component doesn't change. (Be aware that cloning and deep equality checks on large
+ * arrays or objects can have a negative impact on your application performance)
+ *
+ * <example name="doCheckArrayExample" module="do-check-module">
+ *   <file name="index.html">
+ *     <div ng-init="items = []">
+ *       <button ng-click="items.push(items.length)">Add Item</button>
+ *       <button ng-click="items = []">Reset Items</button>
+ *       <pre>{{ items }}</pre>
+ *       <test items="items"></test>
+ *     </div>
+ *   </file>
+ *   <file name="app.js">
+ *      angular.module('do-check-module', [])
+ *        .component('test', {
+ *          bindings: { items: '<' },
+ *          template:
+ *            '<pre>{{ $ctrl.log | json }}</pre>',
+ *          controller: function() {
+ *            this.log = [];
+ *
+ *            this.$doCheck = function() {
+ *              if (this.items_ref !== this.items) {
+ *                this.log.push('doCheck: items changed');
+ *                this.items_ref = this.items;
+ *              }
+ *              if (!angular.equals(this.items_clone, this.items)) {
+ *                this.log.push('doCheck: items mutated');
+ *                this.items_clone = angular.copy(this.items);
+ *              }

+ * ### Directive Definition Object
+ *
+ * The directive definition object provides instructions to the {@link ng.$compile
+ * compiler}. The attributes are:
+ *
+ * #### `multiElement`
+ * When this property is set to true, the HTML compiler will collect DOM nodes between
+ * nodes with the attributes `directive-name-start` and `directive-name-end`, and group them
+ * together as the directive elements. It is recommended that this feature be used on directives
+ * which are not strictly behavioral (such as {@link ngClick}), and which
+ * do not manipulate or replace child nodes (such as {@link ngInclude}).
+ *
+ * #### `priority`
+ * When there are multiple directives defined on a single DOM element, sometimes it
+ * is necessary to specify the order in which the directives are applied. The `priority` is used
+ * to sort the directives before their `compile` functions get called. Priority is defined as a
+ * number. Directives with greater numerical `priority` are compiled first. Pre-link functions
+ * are also run in priority order, but post-link functions are run in reverse order. The order
+ * of directives with the same priority is undefined. The default priority is `0`.
+ *
+ * #### `terminal`
+ * If set to true then the current `priority` will be the last set of directives
+ * which will execute (any directives at the current priority will still execute
+ * as the order of execution on same `priority` is undefined). Note that expressions
+ * and other directives used in the directive's template will also be excluded from execution.
+ *
+ * #### `scope`
+ * The scope property can be `true`, an object or a falsy value:
+ *
+ * * **falsy:** No scope will be created for the directive. The directive will use its parent's scope.
+ *
+ * * **`true`:** A new child scope that prototypically inherits from its parent will be created for
+ * the directive's element. If multiple directives on the same element request a new scope,
+ * only one new scope is created. The new scope rule does not apply for the root of the template
+ * since the root of the template always gets a new scope.
+ *
+ * * **`{...}` (an object hash):** A new "isolate" scope is created for the directive's element. The
+ * 'isolate' scope differs from normal scope in that it does not prototypically inherit from its parent
+ * scope. This is useful when creating reusable components, which should not accidentally read or modify
+ * data in the parent scope.
+ *
+ * The 'isolate' scope object hash defines a set of local scope properties derived from attributes on the
+ * directive's element. These local properties are useful for aliasing values for templates. The keys in
+ * the object hash map to the name of the property on the isolate scope; the values define how the property
+ * is bound to the parent scope, via matching attributes on the directive's element:
+ *
+ * * `@` or `@attr` - bind a local scope property to the value of DOM attribute. The result is
+ *   always a string since DOM attributes are strings. If no `attr` name is specified then the
+ *   attribute name is assumed to be the same as the local name. Given `<my-component
+ *   my-attr="hello {{name}}">` and the isolate scope definition `scope: { localName:'@myAttr' }`,
+ *   the directive's scope property `localName` will reflect the interpolated value of `hello
+ *   {{name}}`. As the `name` attribute changes so will the `localName` property on the directive's
+ *   scope. The `name` is read from the parent scope (not the directive's scope).
+ *
+ * * `=` or `=attr` - set up a bidirectional binding between a local scope property and an expression
+ *   passed via the attribute `attr`. The expression is evaluated in the context of the parent scope.
+ *   If no `attr` name is specified then the attribute name is assumed to be the same as the local
+ *   name. Given `<my-component my-attr="parentModel">` and the isolate scope definition `scope: {
+ *   localModel: '=myAttr' }`, the property `localModel` on the directive's scope will reflect the
+ *   value of `parentModel` on the parent scope. Changes to `parentModel` will be reflected in
+ *   `localModel` and vice versa. Optional attributes should be marked as such with a question mark:
+ *   `=?` or `=?attr`. If the binding expression is non-assignable, or if the attribute isn't
+ *   optional and doesn't exist, an exception ({@link error/$compile/nonassign `$compile:nonassign`})
+ *   will be thrown upon discovering changes to the local value, since it will be impossible to sync
+ *   them back to the parent scope. By default, the {@link ng.$rootScope.Scope#$watch `$watch`}
+ *   method is used for tracking changes, and the equality check is based on object identity.
+ *   However, if an object literal or an array literal is passed as the binding expression, the
+ *   equality check is done by value (using the {@link angular.equals} function). It's also possible
+ *   to watch the evaluated value shallowly with {@link ng.$rootScope.Scope#$watchCollection
+ *   `$watchCollection`}: use `=*` or `=*attr` (`=*?` or `=*?attr` if the attribute is optional).
+ *
+  * * `<` or `<attr` - set up a one-way (one-directional) binding between a local scope property and an
+ *   expression passed via the attribute `attr`. The expression is evaluated in the context of the
+ *   parent scope. If no `attr` name is specified then the attribute name is assumed to be the same as the
+ *   local name. You can also make the binding optional by adding `?`: `<?` or `<?attr`.
+ *
+ *   For example, given `<my-component my-attr="parentModel">` and directive definition of
+ *   `scope: { localModel:'<myAttr' }`, then the isolated scope property `localModel` will reflect the
+ *   value of `parentModel` on the parent scope. Any changes to `parentModel` will be reflected
+ *   in `localModel`, but changes in `localModel` will not reflect in `parentModel`. There are however
+ *   two caveats:
+ *     1. one-way binding does not copy the value from the parent to the isolate scope, it simply
+ *     sets the same value. That means if your bound value is an object, changes to its properties
+ *     in the isolated scope will be reflected in the parent scope (because both reference the same object).
+ *     2. one-way binding watches changes to the **identity** of the parent value. That means the
+ *     {@link ng.$rootScope.Scope#$watch `$watch`} on the parent value only fires if the reference
+ *     to the value has changed. In most cases, this should not be of concern, but can be important
+ *     to know if you one-way bind to an object, and then replace that object in the isolated scope.
+ *     If you now change a property of the object in your parent scope, the change will not be
+ *     propagated to the isolated scope, because the identity of the object on the parent scope
+ *     has not changed. Instead you must assign a new object.
+ *
+ *   One-way binding is useful if you do not plan to propagate changes to your isolated scope bindings
+ *   back to the parent. However, it does not make this completely impossible.
+ *
+ * * `&` or `&attr` - provides a way to execute an expression in the context of the parent scope. If
+ *   no `attr` name is specified then the attribute name is assumed to be the same as the local name.
+ *   Given `<my-component my-attr="count = count + value">` and the isolate scope definition `scope: {
+ *   localFn:'&myAttr' }`, the isolate scope property `localFn` will point to a function wrapper for
+ *   the `count = count + value` expression. Often it's desirable to pass data from the isolated scope
+ *   via an expression to the parent scope. This can be done by passing a map of local variable names
+ *   and values into the expression wrapper fn. For example, if the expression is `increment(amount)`
+ *   then we can specify the amount value by calling the `localFn` as `localFn({amount: 22})`.
+ *
+ * In general it's possible to apply more than one directive to one element, but there might be limitations
+ * depending on the type of scope required by the directives. The following points will help explain these limitations.
+ * For simplicity only two directives are taken into account, but it is also applicable for several directives:
+ *
+ * * **no scope** + **no scope** => Two directives which don't require their own scope will use their parent's scope
+ * * **child scope** + **no scope** =>  Both directives will share one single child scope
+ * * **child scope** + **child scope** =>  Both directives will share one single child scope
+ * * **isolated scope** + **no scope** =>  The isolated directive will use it's own created isolated scope. The other directive will use
+ * its parent's scope
+ * * **isolated scope** + **child scope** =>  **Won't work!** Only one scope can be related to one element. Therefore these directives cannot
+ * be applied to the same element.
+ * * **isolated scope** + **isolated scope**  =>  **Won't work!** Only one scope can be related to one element. Therefore these directives
+ * cannot be applied to the same element.
+ *
+ *
+ * #### `bindToController`
+ * This property is used to bind scope properties directly to the controller. It can be either
+ * `true` or an object hash with the same format as the `scope` property. Additionally, a controller
+ * alias must be set, either by using `controllerAs: 'myAlias'` or by specifying the alias in the controller
+ * definition: `controller: 'myCtrl as myAlias'`.
+ *
+ * When an isolate scope is used for a directive (see above), `bindToController: true` will
+ * allow a component to have its properties bound to the controller, rather than to scope.
+ *
+ * After the controller is instantiated, the initial values of the isolate scope bindings will be bound to the controller
+ * properties. You can access these bindings once they have been initialized by providing a controller method called
+ * `$onInit`, which is called after all the controllers on an element have been constructed and had their bindings
+ * initialized.
+ *
+ * <div class="alert alert-warning">
+ * **Deprecation warning:** although bindings for non-ES6 class controllers are currently
+ * bound to `this` before the controller constructor is called, this use is now deprecated. Please place initialization
+ * code that relies upon bindings inside a `$onInit` method on the controller, instead.
+ * </div>
+ *
+ * It is also possible to set `bindToController` to an object hash with the same format as the `scope` property.
+ * This will set up the scope bindings to the controller directly. Note that `scope` can still be used
+ * to define which kind of scope is created. By default, no scope is created. Use `scope: {}` to create an isolate
+ * scope (useful for component directives).
+ *
+ * If both `bindToController` and `scope` are defined and have object hashes, `bindToController` overrides `scope`.
+ *
+ *
+ * #### `controller`
+ * Controller constructor function. The controller is instantiated before the
+ * pre-linking phase and can be accessed by other directives (see
+ * `require` attribute). This allows the directives to communicate with each other and augment
+ * each other's behavior. The controller is injectable (and supports bracket notation) with the following locals:
+ *
+ * * `$scope` - Current scope associated with the element
+ * * `$element` - Current element
+ * * `$attrs` - Current attributes object for the element
+ * * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope:
+ *   `function([scope], cloneLinkingFn, futureParentElement, slotName)`:
+ *    * `scope`: (optional) override the scope.
+ *    * `cloneLinkingFn`: (optional) argument to create clones of the original transcluded content.
+ *    * `futureParentElement` (optional):
+ *        * defines the parent to which the `cloneLinkingFn` will add the cloned elements.
+ *        * default: `$element.parent()` resp. `$element` for `transclude:'element'` resp. `transclude:true`.
+ *        * only needed for transcludes that are allowed to contain non html elements (e.g. SVG elements)
+ *          and when the `cloneLinkinFn` is passed,
+ *          as those elements need to created and cloned in a special way when they are defined outside their
+ *          usual containers (e.g. like `<svg>`).
+ *        * See also the `directive.templateNamespace` property.
+ *    * `slotName`: (optional) the name of the slot to transclude. If falsy (e.g. `null`, `undefined` or `''`)
+ *      then the default translusion is provided.
+ *    The `$transclude` function also has a method on it, `$transclude.isSlotFilled(slotName)`, which returns
+ *    `true` if the specified slot contains content (i.e. one or more DOM nodes).
+ *
+ * #### `require`
+ * Require another directive and inject its controller as the fourth argument to the linking function. The
+ * `require` property can be a string, an array or an object:
+ * * a **string** containing the name of the directive to pass to the linking function
+ * * an **array** containing the names of directives to pass to the linking function. The argument passed to the
+ * linking function will be an array of controllers in the same order as the names in the `require` property
+ * * an **object** whose property values are the names of the directives to pass to the linking function. The argument
+ * passed to the linking function will also be an object with matching keys, whose values will hold the corresponding
+ * controllers.
+ *
+ * If the `require` property is an object and `bindToController` is truthy, then the required controllers are
+ * bound to the controller using the keys of the `require` property. This binding occurs after all the controllers
+ * have been constructed but before `$onInit` is called.
+ * If the name of the required controller is the same as the local name (the key), the name can be
+ * omitted. For example, `{parentDir: '^^'}` is equivalent to `{parentDir: '^^parentDir'}`.
+ * See the {@link $compileProvider#component} helper for an example of how this can be used.
+ * If no such required directive(s) can be found, or if the directive does not have a controller, then an error is
+ * raised (unless no link function is specified and the required controllers are not being bound to the directive
+ * controller, in which case error checking is skipped). The name can be prefixed with:
+ *
+ * * (no prefix) - Locate the required controller on the current element. Throw an error if not found.
+ * * `?` - Attempt to locate the required controller or pass `null` to the `link` fn if not found.
+ * * `^` - Locate the required controller by searching the element and its parents. Throw an error if not found.
+ * * `^^` - Locate the required controller by searching the element's parents. Throw an error if not found.
+ * * `?^` - Attempt to locate the required controller by searching the element and its parents or pass
+ *   `null` to the `link` fn if not found.
+ * * `?^^` - Attempt to locate the required controller by searching the element's parents, or pass
+ *   `null` to the `link` fn if not found.
+ *
+ *
+ * #### `controllerAs`
+ * Identifier name for a reference to the controller in the directive's scope.
+ * This allows the controller to be referenced from the directive template. This is especially
+ * useful when a directive is used as component, i.e. with an `isolate` scope. It's also possible
+ * to use it in a directive without an `isolate` / `new` scope, but you need to be aware that the
+ * `controllerAs` reference might overwrite a property that already exists on the parent scope.
+ *
+ *
+ * #### `restrict`
+ * String of subset of `EACM` which restricts the directive to a specific directive
+ * declaration style. If omitted, the defaults (elements and attributes) are used.
+ *
+ * * `E` - Element name (default): `<my-directive></my-directive>`
+ * * `A` - Attribute (default): `<div my-directive="exp"></div>`
+ * * `C` - Class: `<div class="my-directive: exp;"></div>`
+ * * `M` - Comment: `<!-- directive: my-directive exp -->`
+ *
+ *
+ * #### `templateNamespace`
+ * String representing the document type used by the markup in the template.
+ * AngularJS needs this information as those elements need to be created and cloned
+ * in a special way when they are defined outside their usual containers like `<svg>` and `<math>`.
+ *
+ * * `html` - All root nodes in the template are HTML. Root nodes may also be
+ *   top-level elements such as `<svg>` or `<math>`.
+ * * `svg` - The root nodes in the template are SVG elements (excluding `<math>`).
+ * * `math` - The root nodes in the template are MathML elements (excluding `<svg>`).
+ *
+ * If no `templateNamespace` is specified, then the namespace is considered to be `html`.
+ *
+ * #### `template`
+ * HTML markup that may:
+ * * Replace the contents of the directive's element (default).
+ * * Replace the directive's element itself (if `replace` is true - DEPRECATED).
+ * * Wrap the contents of the directive's element (if `transclude` is true).
+ *
+ * Value may be:
+ *
+ * * A string. For example `<div red-on-hover>{{delete_str}}</div>`.
+ * * A function which takes two arguments `tElement` and `tAttrs` (described in the `compile`
+ *   function api below) and returns a string value.
+ *
+ *
+ * #### `templateUrl`
+ * This is similar to `template` but the template is loaded from the specified URL, asynchronously.
+ *
+ * Because template loading is asynchronous the compiler will suspend compilation of directives on that element
+ * for later when the template has been resolved.  In the meantime it will continue to compile and link
+ * sibling and parent elements as though this element had not contained any directives.
+ *
+ * The compiler does not suspend the entire compilation to wait for templates to be loaded because this
+ * would result in the whole app "stalling" until all templates are loaded asynchronously - even in the
+ * case when only one deeply nested directive has `templateUrl`.
+ *
+ * Template loading is asynchronous even if the template has been preloaded into the {@link $templateCache}
+ *
+ * You can specify `templateUrl` as a string representing the URL or as a function which takes two
+ * arguments `tElement` and `tAttrs` (described in the `compile` function api below) and returns
+ * a string value representing the url.  In either case, the template URL is passed through {@link
+ * $sce#getTrustedResourceUrl $sce.getTrustedResourceUrl}.
+ *
+ *
+ * #### `replace` ([*DEPRECATED*!], will be removed in next major release - i.e. v2.0)
+ * specify what the template should replace. Defaults to `false`.
+ *
+ * * `true` - the template will replace the directive's element.
+ * * `false` - the template will replace the contents of the directive's element.
+ *
+ * The replacement process migrates all of the attributes / classes from the old element to the new
+ * one. See the {@link guide/directive#template-expanding-directive
+ * Directives Guide} for an example.
+ *
+ * There are very few scenarios where element replacement is required for the application function,
+ * the main one being reusable custom components that are used within SVG contexts
+ * (because SVG doesn't work with custom elements in the DOM tree).
+ *
+ * #### `transclude`
+ * Extract the contents of the element where the directive appears and make it available to the directive.
+ * The contents are compiled and provided to the directive as a **transclusion function**. See the
+ * {@link $compile#transclusion Transclusion} section below.
+ *
+ *
+ * #### `compile`
+ *
+ * ```js
+ *   function compile(tElement, tAttrs, transclude) { ... }
+ * ```
+ *
+ * The compile function deals with transforming the template DOM. Since most directives do not do
+ * template transformation, it is not used often. The compile function takes the following arguments:
+ *
+ *   * `tElement` - template element - The element where the directive has been declared. It is
+ *     safe to do template transformation on the element and child elements only.
+ *
+ *   * `tAttrs` - template attributes - Normalized list of attributes declared on this element shared
+ *     between all directive compile functions.
+ *
+ *   * `transclude` -  [*DEPRECATED*!] A transclude linking function: `function(scope, cloneLinkingFn)`
+ *
+ * <div class="alert alert-warning">
+ * **Note:** The template instance and the link instance may be different objects if the template has
+ * been cloned. For this reason it is **not** safe to do anything other than DOM transformations that
+ * apply to all cloned DOM nodes within the compile function. Specifically, DOM listener registration
+ * should be done in a linking function rather than in a compile function.
+ * </div>
+
+ * <div class="alert alert-warning">
+ * **Note:** The compile function cannot handle directives that recursively use themselves in their
+ * own templates or compile functions. Compiling these directives results in an infinite loop and
+ * stack overflow errors.
+ *
+ * This can be avoided by manually using $compile in the postLink function to imperatively compile
+ * a directive's template instead of relying on automatic template compilation via `template` or
+ * `templateUrl` declaration or manual compilation inside the compile function.
+ * </div>
+ *
+ * <div class="alert alert-danger">
+ * **Note:** The `transclude` function that is passed to the compile function is deprecated, as it
+ *   e.g. does not know about the right outer scope. Please use the transclude function that is passed
+ *   to the link function instead.
+ * </div>
+
+ * A compile function can have a return value which can be either a function or an object.
+ *
+ * * returning a (post-link) function - is equivalent to registering the linking function via the
+ *   `link` property of the config object when the compile function is empty.
+ *
+ * * returning an object with function(s) registered via `pre` and `post` properties - allows you to
+ *   control when a linking function should be called during the linking phase. See info about
+ *   pre-linking and post-linking functions below.
+ *
+ *
+ * #### `link`
+ * This property is used only if the `compile` property is not defined.
+ *
+ * ```js
+ *   function link(scope, iElement, iAttrs, controller, transcludeFn) { ... }
+ * ```
+ *
+ * The link function is responsible for registering DOM listeners as well as updating the DOM. It is
+ * executed after the template has been cloned. This is where most of the directive logic will be
+ * put.
+ *
+ *   * `scope` - {@link ng.$rootScope.Scope Scope} - The scope to be used by the
+ *     directive for registering {@link ng.$rootScope.Scope#$watch watches}.
+ *
+ *   * `iElement` - instance element - The element where the directive is to be used. It is safe to
+ *     manipulate the children of the element only in `postLink` function since the children have
+ *     already been linked.
+ *
+ *   * `iAttrs` - instance attributes - Normalized list of attributes declared on this element shared
+ *     between all directive linking functions.
+ *
+ *   * `controller` - the directive's required controller instance(s) - Instances are shared
+ *     among all directives, which allows the directives to use the controllers as a communication
+ *     channel. The exact value depends on the directive's `require` property:
+ *       * no controller(s) required: the directive's own controller, or `undefined` if it doesn't have one
+ *       * `string`: the controller instance
+ *       * `array`: array of controller instances
+ *
+ *     If a required controller cannot be found, and it is optional, the instance is `null`,
+ *     otherwise the {@link error:$compile:ctreq Missing Required Controller} error is thrown.
+ *
+ *     Note that you can also require the directive's own controller - it will be made available like
+ *     any other controller.
+ *
+ *   * `transcludeFn` - A transclude linking function pre-bound to the correct transclusion scope.
+ *     This is the same as the `$transclude` parameter of directive controllers,
+ *     see {@link ng.$compile#-controller- the controller section for details}.
+ *     `function([scope], cloneLinkingFn, futureParentElement)`.
+ *
+ * #### Pre-linking function
+ *
+ * Executed before the child elements are linked. Not safe to do DOM transformation since the
+ * compiler linking function will fail to locate the correct elements for linking.
+ *
+ * #### Post-linking function
+ *
+ * Executed after the child elements are linked.
+ *
+ * Note that child elements that contain `templateUrl` directives will not have been compiled
+ * and linked since they are waiting for their template to load asynchronously and their own
+ * compilation and linking has been suspended until that occurs.
+ *
+ * It is safe to do DOM transformation in the post-linking function on elements that are not waiting
+ * for their async templates to be resolved.
+ *
+ *
+ * ### Transclusion
+ *
+ * Transclusion is the process of extracting a collection of DOM elements from one part of the DOM and
+ * copying them to another part of the DOM, while maintaining their connection to the original AngularJS
+ * scope from where they were taken.
+ *
+ * Transclusion is used (often with {@link ngTransclude}) to insert the
+ * original contents of a directive's element into a specified place in the template of the directive.
+ * The benefit of transclusion, over simply moving the DOM elements manually, is that the transcluded
+ * content has access to the properties on the scope from which it was taken, even if the directive
+ * has isolated scope.
+ * See the {@link guide/directive#creating-a-directive-that-wraps-other-elements Directives Guide}.
+ *
+ * This makes it possible for the widget to have private state for its template, while the transcluded
+ * content has access to its originating scope.
+ *
+ * <div class="alert alert-warning">
+ * **Note:** When testing an element transclude directive you must not place the directive at the root of the
+ * DOM fragment that is being compiled. See {@link guide/unit-testing#testing-transclusion-directives
+ * Testing Transclusion Directives}.
+ * </div>
+ *
+ * There are three kinds of transclusion depending upon whether you want to transclude just the contents of the
+ * directive's element, the entire element or multiple parts of the element contents:
+ *
+ * * `true` - transclude the content (i.e. the child nodes) of the directive's element.
+ * * `'element'` - transclude the whole of the directive's element including any directives on this
+ *   element that defined at a lower priority than this directive. When used, the `template`
+ *   property is ignored.
+ * * **`{...}` (an object hash):** - map elements of the content onto transclusion "slots" in the template.
+ *
+ * **Mult-slot transclusion** is declared by providing an object for the `transclude` property.
+ *
+ * This object is a map where the keys are the name of the slot to fill and the value is an element selector
+ * used to match the HTML to the slot. The element selector should be in normalized form (e.g. `myElement`)
+ * and will match the standard element variants (e.g. `my-element`, `my:element`, `data-my-element`, etc).
+ *
+ * For further information check out the guide on {@link guide/directive#matching-directives Matching Directives}
+ *
+ * If the element selector is prefixed with a `?` then that slot is optional.
+ *
+ * For example, the transclude object `{ slotA: '?myCustomElement' }` maps `<my-custom-element>` elements to
+ * the `slotA` slot, which can be accessed via the `$transclude` function or via the {@link ngTransclude} directive.
+ *
+ * Slots that are not marked as optional (`?`) will trigger a compile time error if there are no matching elements
+ * in the transclude content. If you wish to know if an optional slot was filled with content, then you can call
+ * `$transclude.isSlotFilled(slotName)` on the transclude function passed to the directive's link function and
+ * injectable into the directive's controller.
+ *
+ *
+ * #### Transclusion Functions
+ *
+ * When a directive requests transclusion, the compiler extracts its contents and provides a **transclusion
+ * function** to the directive's `link` function and `controller`. This transclusion function is a special
+ * **linking function** that will return the compiled contents linked to a new transclusion scope.
+ *
+ * <div class="alert alert-info">
+ * If you are just using {@link ngTransclude} then you don't need to worry about this function, since
+ * ngTransclude will deal with it for us.
+ * </div>
+ *
+ * If you want to manually control the insertion and removal of the transcluded content in your directive
+ * then you must use this transclude function. When you call a transclude function it returns a a jqLite/JQuery
+ * object that contains the compiled DOM, which is linked to the correct transclusion scope.
+ *
+ * When you call a transclusion function you can pass in a **clone attach function**. This function accepts
+ * two parameters, `function(clone, scope) { ... }`, where the `clone` is a fresh compiled copy of your transcluded
+ * content and the `scope` is the newly created transclusion scope, to which the clone is bound.
+ *
+ * <div class="alert alert-info">
+ * **Best Practice**: Always provide a `cloneFn` (clone attach function) when you call a transclude function
+ * since you then get a fresh clone of the original DOM and also have access to the new transclusion scope.
+ * </div>
+ *
+ * It is normal practice to attach your transcluded content (`clone`) to the DOM inside your **clone
+ * attach function**:
+ *
+ * ```js
+ * var transcludedContent, transclusionScope;
+ *
+ * $transclude(function(clone, scope) {
+ *   element.append(clone);
+ *   transcludedContent = clone;
+ *   transclusionScope = scope;
+ * });
+ * ```
+ *
+ * Later, if you want to remove the transcluded content from your DOM then you should also destroy the
+ * associated transclusion scope:
+ *
+ * ```js
+ * transcludedContent.remove();
+ * transclusionScope.$destroy();
+ * ```
+ *
+ * <div class="alert alert-info">
+ * **Best Practice**: if you intend to add and remove transcluded content manually in your directive
+ * (by calling the transclude function to get the DOM and calling `element.remove()` to remove it),
+ * then you are also responsible for calling `$destroy` on the transclusion scope.
+ * </div>
+ *
+ * The built-in DOM manipulation directives, such as {@link ngIf}, {@link ngSwitch} and {@link ngRepeat}
+ * automatically destroy their transcluded clones as necessary so you do not need to worry about this if
+ * you are simply using {@link ngTransclude} to inject the transclusion into your directive.
+ *
+ *
+ * #### Transclusion Scopes
+ *
+ * When you call a transclude function it returns a DOM fragment that is pre-bound to a **transclusion
+ * scope**. This scope is special, in that it is a child of the directive's scope (and so gets destroyed
+ * when the directive's scope gets destroyed) but it inherits the properties of the scope from which it
+ * was taken.
+ *
+ * For example consider a directive that uses transclusion and isolated scope. The DOM hierarchy might look
+ * like this:
+ *
+ * ```html
+ * <div ng-app>
+ *   <div isolate>
+ *     <div transclusion>
+ *     </div>
+ *   </div>
+ * </div>
+ * ```
+ *
+ * The `$parent` scope hierarchy will look like this:
+ *
+   ```
+   - $rootScope
+     - isolate
+       - transclusion
+   ```
+ *
+ * but the scopes will inherit prototypically from different scopes to their `$parent`.
+ *
+   ```
+   - $rootScope
+     - transclusion
+   - isolate
+   ```
+ *
+ *
+ * ### Attributes
+ *
+ * The {@link ng.$compile.directive.Attributes Attributes} object - passed as a parameter in the
+ * `link()` or `compile()` functions. It has a variety of uses.
+ *
+ * * *Accessing normalized attribute names:* Directives like 'ngBind' can be expressed in many ways:
+ *   'ng:bind', `data-ng-bind`, or 'x-ng-bind'. The attributes object allows for normalized access
+ *   to the attributes.
+ *
+ * * *Directive inter-communication:* All directives share the same instance of the attributes
+ *   object which allows the directives to use the attributes object as inter directive
+ *   communication.
+ *
+ * * *Supports interpolation:* Interpolation attributes are assigned to the attribute object
+ *   allowing other directives to read the interpolated value.
+ *
+ * * *Observing interpolated attributes:* Use `$observe` to observe the value changes of attributes
+ *   that contain interpolation (e.g. `src="{{bar}}"`). Not only is this very efficient but it's also
+ *   the only way to easily get the actual value because during the linking phase the interpolation
+ *   hasn't been evaluated yet and so the value is at this time set to `undefined`.
+ *
+ * ```js
+ * function linkingFn(scope, elm, attrs, ctrl) {
+ *   // get the attribute value
+ *   console.log(attrs.ngModel);
+ *
+ *   // change the attribute
+ *   attrs.$set('ngModel', 'new value');
+ *
+ *   // observe changes to interpolated attribute
+ *   attrs.$observe('ngModel', function(value) {
+ *     console.log('ngModel has changed value to ' + value);
+ *   });
+ * }
+ * ```

+ * (a DOM element/tree) to a scope. Where:
+ *
+ *  * `scope` - A {@link ng.$rootScope.Scope Scope} to bind to.
+ *  * `cloneAttachFn` - If `cloneAttachFn` is provided, then the link function will clone the
+ *  `template` and call the `cloneAttachFn` function allowing the caller to attach the
+ *  cloned elements to the DOM document at the appropriate place. The `cloneAttachFn` is
+ *  called as: <br/> `cloneAttachFn(clonedElement, scope)` where:
+ *
+ *      * `clonedElement` - is a clone of the original `element` passed into the compiler.
+ *      * `scope` - is the current scope with which the linking function is working with.
+ *
+ *  * `options` - An optional object hash with linking options. If `options` is provided, then the following
+ *  keys may be used to control linking behavior:
+ *
+ *      * `parentBoundTranscludeFn` - the transclude function made available to
+ *        directives; if given, it will be passed through to the link functions of
+ *        directives found in `element` during compilation.
+ *      * `transcludeControllers` - an object hash with keys that map controller names
+ *        to a hash with the key `instance`, which maps to the controller instance;
+ *        if given, it will make the controllers available to directives on the compileNode:
+ *        ```
+ *        {
+ *          parent: {
+ *            instance: parentControllerInstance
+ *          }
+ *        }
+ *        ```
+ *      * `futureParentElement` - defines the parent to which the `cloneAttachFn` will add
+ *        the cloned elements; only needed for transcludes that are allowed to contain non html
+ *        elements (e.g. SVG elements). See also the directive.controller property.
+ *
+ * Calling the linking function returns the element of the template. It is either the original
+ * element passed in, or the clone of the element if the `cloneAttachFn` is provided.
+ *
+ * After linking the view is not updated until after a call to $digest which typically is done by
+ * Angular automatically.
+ *
+ * If you need access to the bound view, there are two ways to do it:
+ *
+ * - If you are not asking the linking function to clone the template, create the DOM element(s)
+ *   before you send them to the compiler and keep this reference around.
+ *   ```js
+ *     var element = $compile('<p>{{total}}</p>')(scope);
+ *   ```
+ *
+ * - if on the other hand, you need the element to be cloned, the view reference from the original
+ *   example would not point to the clone, but rather to the original template that was cloned. In
+ *   this case, you can access the clone via the cloneAttachFn:
+ *   ```js
+ *     var templateElement = angular.element('<p>{{total}}</p>'),
+ *         scope = ....;
+ *
+ *     var clonedElement = $compile(templateElement)(scope, function(clonedElement, scope) {
+ *       //attach the clone to DOM document at the right place
+ *     });
+ *
+ *     //now we have reference to the cloned DOM via `clonedElement`
+ *   ```
+ *
+ *

+ * {@link guide/compiler Angular HTML Compiler} section of the Developer Guide.

+   * Register a **component definition** with the compiler. This is a shorthand for registering a special
+   * type of directive, which represents a self-contained UI component in your application. Such components
+   * are always isolated (i.e. `scope: {}`) and are always restricted to elements (i.e. `restrict: 'E'`).
+   *
+   * Component definitions are very simple and do not require as much configuration as defining general
+   * directives. Component definitions usually consist only of a template and a controller backing it.
+   *
+   * In order to make the definition easier, components enforce best practices like use of `controllerAs`,
+   * `bindToController`. They always have **isolate scope** and are restricted to elements.
+   *
+   * Here are a few examples of how you would usually define components:
+   *
+   * ```js
+   *   var myMod = angular.module(...);
+   *   myMod.component('myComp', {
+   *     template: '<div>My name is {{$ctrl.name}}</div>',
+   *     controller: function() {
+   *       this.name = 'shahar';
+   *     }
+   *   });
+   *
+   *   myMod.component('myComp', {
+   *     template: '<div>My name is {{$ctrl.name}}</div>',
+   *     bindings: {name: '@'}

+   *     controller: 'MyCtrl',
+   *     controllerAs: 'ctrl',
+   *     bindings: {name: '@'}
+   *   });

+ *
+ * In unit tests, if `angular-mocks.js` is loaded, this service is overridden by

+ *
+ * ## Example:
+ *
+ * The example below will overwrite the default `$exceptionHandler` in order to (a) log uncaught
+ * errors to the backend for later inspection by the developers and (b) to use `$log.warn()` instead
+ * of `$log.error()`.
+ *
+ * ```js
+ *   angular.
+ *     module('exceptionOverwrite', []).
+ *     factory('$exceptionHandler', ['$log', 'logErrorsToBackend', function($log, logErrorsToBackend) {

+ *       };
+ *     }]);
+ * ```
+ *
+ * <hr />
+ * Note, that code executed in event-listeners (even those registered using jqLite's `on`/`bind`
+ * methods) does not delegate exceptions to the {@link ng.$exceptionHandler $exceptionHandler}
+ * (unless executed during a digest).
+ *
+ * If you wish, you can manually delegate exceptions, e.g.
+ * `try { ... } catch(e) { $exceptionHandler(e); }`

+     * @description
+     * The `$http` service is a core Angular service that facilitates communication with the remote
+     * HTTP servers via the browser's [XMLHttpRequest](https://developer.mozilla.org/en/xmlhttprequest)
+     * object or via [JSONP](http://en.wikipedia.org/wiki/JSONP).
+     *
+     * For unit testing applications that use `$http` service, see
+     * {@link ngMock.$httpBackend $httpBackend mock}.
+     *
+     * For a higher level of abstraction, please check out the {@link ngResource.$resource
+     * $resource} service.
+     *
+     * The $http API is based on the {@link ng.$q deferred/promise APIs} exposed by
+     * the $q service. While for simple usage patterns this doesn't matter much, for advanced usage
+     * it is important to familiarize yourself with these APIs and the guarantees they provide.
+     *
+     *
+     * ## General usage
+     * The `$http` service is a function which takes a single argument — a {@link $http#usage configuration object} —
+     * that is used to generate an HTTP request and returns  a {@link ng.$q promise}.
+     *
+     * ```js
+     *   // Simple GET request example:
+     *   $http({
+     *     method: 'GET',
+     *     url: '/someUrl'
+     *   }).then(function successCallback(response) {
+     *       // this callback will be called asynchronously
+     *       // when the response is available
+     *     }, function errorCallback(response) {
+     *       // called asynchronously if an error occurs
+     *       // or server returns response with an error status.
+     *     });
+     * ```
+     *
+     * The response object has these properties:
+     *
+     *   - **data** – `{string|Object}` – The response body transformed with the transform
+     *     functions.
+     *   - **status** – `{number}` – HTTP status code of the response.
+     *   - **headers** – `{function([headerName])}` – Header getter function.
+     *   - **config** – `{Object}` – The configuration object that was used to generate the request.
+     *   - **statusText** – `{string}` – HTTP status text of the response.
+     *
+     * A response status code between 200 and 299 is considered a success status and will result in
+     * the success callback being called. Any response status code outside of that range is
+     * considered an error status and will result in the error callback being called.
+     * Also, status codes less than -1 are normalized to zero. -1 usually means the request was
+     * aborted, e.g. using a `config.timeout`.
+     * Note that if the response is a redirect, XMLHttpRequest will transparently follow it, meaning
+     * that the outcome (success or error) will be determined by the final response status code.
+     *
+     *
+     * ## Shortcut methods
+     *
+     * Shortcut methods are also available. All shortcut methods require passing in the URL, and
+     * request data must be passed in for POST/PUT requests. An optional config can be passed as the
+     * last argument.
+     *
+     * ```js
+     *   $http.get('/someUrl', config).then(successCallback, errorCallback);
+     *   $http.post('/someUrl', data, config).then(successCallback, errorCallback);
+     * ```
+     *
+     * Complete list of shortcut methods:
+     *
+     * - {@link ng.$http#get $http.get}
+     * - {@link ng.$http#head $http.head}
+     * - {@link ng.$http#post $http.post}
+     * - {@link ng.$http#put $http.put}
+     * - {@link ng.$http#delete $http.delete}
+     * - {@link ng.$http#jsonp $http.jsonp}
+     * - {@link ng.$http#patch $http.patch}
+     *
+     *
+     * ## Writing Unit Tests that use $http
+     * When unit testing (using {@link ngMock ngMock}), it is necessary to call
+     * {@link ngMock.$httpBackend#flush $httpBackend.flush()} to flush each pending
+     * request using trained responses.
+     *
+     * ```
+     * $httpBackend.expectGET(...);
+     * $http.get(...);
+     * $httpBackend.flush();
+     * ```
+     *
+     * ## Deprecation Notice
+     * <div class="alert alert-danger">
+     *   The `$http` legacy promise methods `success` and `error` have been deprecated.
+     *   Use the standard `then` method instead.
+     *   If {@link $httpProvider#useLegacyPromiseExtensions `$httpProvider.useLegacyPromiseExtensions`} is set to
+     *   `false` then these methods will throw {@link $http:legacy `$http/legacy`} error.
+     * </div>
+     *
+     * ## Setting HTTP Headers
+     *
+     * The $http service will automatically add certain HTTP headers to all requests. These defaults
+     * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration
+     * object, which currently contains this default configuration:
+     *
+     * - `$httpProvider.defaults.headers.common` (headers that are common for all requests):
+     *   - `Accept: application/json, text/plain, * / *`
+     * - `$httpProvider.defaults.headers.post`: (header defaults for POST requests)
+     *   - `Content-Type: application/json`
+     * - `$httpProvider.defaults.headers.put` (header defaults for PUT requests)
+     *   - `Content-Type: application/json`
+     *
+     * To add or overwrite these defaults, simply add or remove a property from these configuration
+     * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object
+     * with the lowercased HTTP method name as the key, e.g.
+     * `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }`.
+     *
+     * The defaults can also be set at runtime via the `$http.defaults` object in the same
+     * fashion. For example:
+     *
+     * ```
+     * module.run(function($http) {
+     *   $http.defaults.headers.common.Authorization = 'Basic YmVlcDpib29w';
+     * });
+     * ```
+     *
+     * In addition, you can supply a `headers` property in the config object passed when
+     * calling `$http(config)`, which overrides the defaults without changing them globally.
+     *
+     * To explicitly remove a header automatically added via $httpProvider.defaults.headers on a per request basis,
+     * Use the `headers` property, setting the desired header to `undefined`. For example:
+     *
+     * ```js
+     * var req = {
+     *  method: 'POST',
+     *  url: 'http://example.com',
+     *  headers: {
+     *    'Content-Type': undefined
+     *  },
+     *  data: { test: 'test' }
+     * }
+     *
+     * $http(req).then(function(){...}, function(){...});
+     * ```
+     *
+     * ## Transforming Requests and Responses
+     *
+     * Both requests and responses can be transformed using transformation functions: `transformRequest`
+     * and `transformResponse`. These properties can be a single function that returns
+     * the transformed value (`function(data, headersGetter, status)`) or an array of such transformation functions,
+     * which allows you to `push` or `unshift` a new transformation function into the transformation chain.
+     *
+     * <div class="alert alert-warning">
+     * **Note:** Angular does not make a copy of the `data` parameter before it is passed into the `transformRequest` pipeline.
+     * That means changes to the properties of `data` are not local to the transform function (since Javascript passes objects by reference).
+     * For example, when calling `$http.get(url, $scope.myObject)`, modifications to the object's properties in a transformRequest
+     * function will be reflected on the scope and in any templates where the object is data-bound.
+     * To prevent this, transform functions should have no side-effects.
+     * If you need to modify properties, it is recommended to make a copy of the data, or create new object to return.
+     * </div>
+     *
+     * ### Default Transformations
+     *
+     * The `$httpProvider` provider and `$http` service expose `defaults.transformRequest` and
+     * `defaults.transformResponse` properties. If a request does not provide its own transformations
+     * then these will be applied.
+     *
+     * You can augment or replace the default transformations by modifying these properties by adding to or
+     * replacing the array.
+     *
+     * Angular provides the following default transformations:
+     *
+     * Request transformations (`$httpProvider.defaults.transformRequest` and `$http.defaults.transformRequest`):
+     *
+     * - If the `data` property of the request configuration object contains an object, serialize it
+     *   into JSON format.
+     *
+     * Response transformations (`$httpProvider.defaults.transformResponse` and `$http.defaults.transformResponse`):
+     *
+     *  - If XSRF prefix is detected, strip it (see Security Considerations section below).
+     *  - If JSON response is detected, deserialize it using a JSON parser.
+     *
+     *
+     * ### Overriding the Default Transformations Per Request
+     *
+     * If you wish to override the request/response transformations only for a single request then provide
+     * `transformRequest` and/or `transformResponse` properties on the configuration object passed
+     * into `$http`.
+     *
+     * Note that if you provide these properties on the config object the default transformations will be
+     * overwritten. If you wish to augment the default transformations then you must include them in your
+     * local transformation array.
+     *
+     * The following code demonstrates adding a new response transformation to be run after the default response
+     * transformations have been run.
+     *
+     * ```js
+     * function appendTransform(defaults, transform) {
+     *
+     *   // We can't guarantee that the default transformation is an array
+     *   defaults = angular.isArray(defaults) ? defaults : [defaults];
+     *
+     *   // Append the new transformation to the defaults
+     *   return defaults.concat(transform);
+     * }
+     *
+     * $http({
+     *   url: '...',
+     *   method: 'GET',
+     *   transformResponse: appendTransform($http.defaults.transformResponse, function(value) {
+     *     return doTransform(value);
+     *   })
+     * });
+     * ```
+     *
+     *
+     * ## Caching
+     *
+     * {@link ng.$http `$http`} responses are not cached by default. To enable caching, you must
+     * set the config.cache value or the default cache value to TRUE or to a cache object (created
+     * with {@link ng.$cacheFactory `$cacheFactory`}). If defined, the value of config.cache takes
+     * precedence over the default cache value.
+     *
+     * In order to:
+     *   * cache all responses - set the default cache value to TRUE or to a cache object
+     *   * cache a specific response - set config.cache value to TRUE or to a cache object
+     *
+     * If caching is enabled, but neither the default cache nor config.cache are set to a cache object,
+     * then the default `$cacheFactory("$http")` object is used.
+     *
+     * The default cache value can be set by updating the
+     * {@link ng.$http#defaults `$http.defaults.cache`} property or the
+     * {@link $httpProvider#defaults `$httpProvider.defaults.cache`} property.
+     *
+     * When caching is enabled, {@link ng.$http `$http`} stores the response from the server using
+     * the relevant cache object. The next time the same request is made, the response is returned
+     * from the cache without sending a request to the server.
+     *
+     * Take note that:
+     *
+     *   * Only GET and JSONP requests are cached.
+     *   * The cache key is the request URL including search parameters; headers are not considered.
+     *   * Cached responses are returned asynchronously, in the same way as responses from the server.
+     *   * If multiple identical requests are made using the same cache, which is not yet populated,
+     *     one request will be made to the server and remaining requests will return the same response.
+     *   * A cache-control header on the response does not affect if or how responses are cached.
+     *
+     *
+     * ## Interceptors
+     *
+     * Before you start creating interceptors, be sure to understand the
+     * {@link ng.$q $q and deferred/promise APIs}.
+     *
+     * For purposes of global error handling, authentication, or any kind of synchronous or
+     * asynchronous pre-processing of request or postprocessing of responses, it is desirable to be
+     * able to intercept requests before they are handed to the server and
+     * responses before they are handed over to the application code that
+     * initiated these requests. The interceptors leverage the {@link ng.$q
+     * promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing.
+     *
+     * The interceptors are service factories that are registered with the `$httpProvider` by
+     * adding them to the `$httpProvider.interceptors` array. The factory is called and
+     * injected with dependencies (if specified) and returns the interceptor.
+     *
+     * There are two kinds of interceptors (and two kinds of rejection interceptors):
+     *
+     *   * `request`: interceptors get called with a http {@link $http#usage config} object. The function is free to
+     *     modify the `config` object or create a new one. The function needs to return the `config`
+     *     object directly, or a promise containing the `config` or a new `config` object.
+     *   * `requestError`: interceptor gets called when a previous interceptor threw an error or
+     *     resolved with a rejection.
+     *   * `response`: interceptors get called with http `response` object. The function is free to
+     *     modify the `response` object or create a new one. The function needs to return the `response`
+     *     object directly, or as a promise containing the `response` or a new `response` object.
+     *   * `responseError`: interceptor gets called when a previous interceptor threw an error or
+     *     resolved with a rejection.
+     *
+     *
+     * ```js
+     *   // register the interceptor as a service
+     *   $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {
+     *     return {
+     *       // optional method
+     *       'request': function(config) {
+     *         // do something on success
+     *         return config;
+     *       },
+     *
+     *       // optional method
+     *      'requestError': function(rejection) {
+     *         // do something on error
+     *         if (canRecover(rejection)) {
+     *           return responseOrNewPromise
+     *         }
+     *         return $q.reject(rejection);
+     *       },
+     *
+     *
+     *
+     *       // optional method
+     *       'response': function(response) {
+     *         // do something on success
+     *         return response;
+     *       },
+     *
+     *       // optional method
+     *      'responseError': function(rejection) {
+     *         // do something on error
+     *         if (canRecover(rejection)) {
+     *           return responseOrNewPromise
+     *         }
+     *         return $q.reject(rejection);
+     *       }
+     *     };
+     *   });
+     *
+     *   $httpProvider.interceptors.push('myHttpInterceptor');
+     *
+     *
+     *   // alternatively, register the interceptor via an anonymous factory
+     *   $httpProvider.interceptors.push(function($q, dependency1, dependency2) {
+     *     return {
+     *      'request': function(config) {
+     *          // same as above
+     *       },
+     *
+     *       'response': function(response) {
+     *          // same as above
+     *       }
+     *     };
+     *   });
+     * ```
+     *
+     * ## Security Considerations
+     *
+     * When designing web applications, consider security threats from:
+     *
+     * - [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
+     * - [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery)
+     *
+     * Both server and the client must cooperate in order to eliminate these threats. Angular comes
+     * pre-configured with strategies that address these issues, but for this to work backend server
+     * cooperation is required.
+     *
+     * ### JSON Vulnerability Protection
+     *
+     * A [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx)
+     * allows third party website to turn your JSON resource URL into
+     * [JSONP](http://en.wikipedia.org/wiki/JSONP) request under some conditions. To
+     * counter this your server can prefix all JSON requests with following string `")]}',\n"`.
+     * Angular will automatically strip the prefix before processing it as JSON.
+     *
+     * For example if your server needs to return:
+     * ```js
+     * ['one','two']
+     * ```
+     *
+     * which is vulnerable to attack, your server can return:
+     * ```js
+     * )]}',
+     * ['one','two']
+     * ```
+     *
+     * Angular will strip the prefix, before processing the JSON.
+     *
+     *
+     * ### Cross Site Request Forgery (XSRF) Protection
+     *
+     * [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) is an attack technique by
+     * which the attacker can trick an authenticated user into unknowingly executing actions on your
+     * website. Angular provides a mechanism to counter XSRF. When performing XHR requests, the
+     * $http service reads a token from a cookie (by default, `XSRF-TOKEN`) and sets it as an HTTP
+     * header (`X-XSRF-TOKEN`). Since only JavaScript that runs on your domain could read the
+     * cookie, your server can be assured that the XHR came from JavaScript running on your domain.
+     * The header will not be set for cross-domain requests.
+     *
+     * To take advantage of this, your server needs to set a token in a JavaScript readable session
+     * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the
+     * server can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure
+     * that only JavaScript running on your domain could have sent the request. The token must be
+     * unique for each user and must be verifiable by the server (to prevent the JavaScript from
+     * making up its own tokens). We recommend that the token is a digest of your site's
+     * authentication cookie with a [salt](https://en.wikipedia.org/wiki/Salt_(cryptography&#41;)
+     * for added security.
+     *
+     * The name of the headers can be specified using the xsrfHeaderName and xsrfCookieName
+     * properties of either $httpProvider.defaults at config-time, $http.defaults at run-time,
+     * or the per-request config object.
+     *
+     * In order to prevent collisions in environments where multiple Angular apps share the
+     * same domain or subdomain, we recommend that each application uses unique cookie name.
+     *
+     * @param {object} config Object describing the request to be made and how it should be
+     *    processed. The object has following properties:
+     *
+     *    - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc)
+     *    - **url** – `{string}` – Absolute or relative URL of the resource that is being requested.
+     *    - **params** – `{Object.<string|Object>}` – Map of strings or objects which will be serialized
+     *      with the `paramSerializer` and appended as GET parameters.
+     *    - **data** – `{string|Object}` – Data to be sent as the request message data.
+     *    - **headers** – `{Object}` – Map of strings or functions which return strings representing
+     *      HTTP headers to send to the server. If the return value of a function is null, the
+     *      header will not be sent. Functions accept a config object as an argument.
+     *    - **eventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest object.
+     *      To bind events to the XMLHttpRequest upload object, use `uploadEventHandlers`.
+     *      The handler will be called in the context of a `$apply` block.
+     *    - **uploadEventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest upload
+     *      object. To bind events to the XMLHttpRequest object, use `eventHandlers`.
+     *      The handler will be called in the context of a `$apply` block.
+     *    - **xsrfHeaderName** – `{string}` – Name of HTTP header to populate with the XSRF token.
+     *    - **xsrfCookieName** – `{string}` – Name of cookie containing the XSRF token.
+     *    - **transformRequest** –
+     *      `{function(data, headersGetter)|Array.<function(data, headersGetter)>}` –
+     *      transform function or an array of such functions. The transform function takes the http
+     *      request body and headers and returns its transformed (typically serialized) version.
+     *      See {@link ng.$http#overriding-the-default-transformations-per-request
+     *      Overriding the Default Transformations}
+     *    - **transformResponse** –
+     *      `{function(data, headersGetter, status)|Array.<function(data, headersGetter, status)>}` –
+     *      transform function or an array of such functions. The transform function takes the http
+     *      response body, headers and status and returns its transformed (typically deserialized) version.
+     *      See {@link ng.$http#overriding-the-default-transformations-per-request
+     *      Overriding the Default Transformations}
+     *    - **paramSerializer** - `{string|function(Object<string,string>):string}` - A function used to
+     *      prepare the string representation of request parameters (specified as an object).
+     *      If specified as string, it is interpreted as function registered with the
+     *      {@link $injector $injector}, which means you can create your own serializer
+     *      by registering it as a {@link auto.$provide#service service}.
+     *      The default serializer is the {@link $httpParamSerializer $httpParamSerializer};
+     *      alternatively, you can use the {@link $httpParamSerializerJQLike $httpParamSerializerJQLike}
+     *    - **cache** – `{boolean|Object}` – A boolean value or object created with
+     *      {@link ng.$cacheFactory `$cacheFactory`} to enable or disable caching of the HTTP response.
+     *      See {@link $http#caching $http Caching} for more information.
+     *    - **timeout** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise}
+     *      that should abort the request when resolved.
+     *    - **withCredentials** - `{boolean}` - whether to set the `withCredentials` flag on the
+     *      XHR object. See [requests with credentials](https://developer.mozilla.org/docs/Web/HTTP/Access_control_CORS#Requests_with_credentials)
+     *      for more information.
+     *    - **responseType** - `{string}` - see
+     *      [XMLHttpRequest.responseType](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest#xmlhttprequest-responsetype).
+     *
+     * @returns {HttpPromise} Returns a {@link ng.$q `Promise}` that will be resolved to a response object
+     *                        when the request succeeds or fails.
+     *
+     *
+     * @property {Array.<Object>} pendingRequests Array of config objects for currently pending
+     *   requests. This is primarily meant to be used for debugging purposes.
+     *

+     * Compiles a string with markup into an interpolation function. This service is used by the
+     * HTML {@link ng.$compile $compile} service for data binding. See
+     * {@link ng.$interpolateProvider $interpolateProvider} for configuring the
+     * interpolation markup.
+     *
+     *
+     * ```js
+     *   var $interpolate = ...; // injected
+     *   var exp = $interpolate('Hello {{name | uppercase}}!');
+     *   expect(exp({name:'Angular'})).toEqual('Hello ANGULAR!');
+     * ```
+     *
+     * `$interpolate` takes an optional fourth argument, `allOrNothing`. If `allOrNothing` is
+     * `true`, the interpolation function will return `undefined` unless all embedded expressions
+     * evaluate to a value other than `undefined`.
+     *
+     * ```js
+     *   var $interpolate = ...; // injected
+     *   var context = {greeting: 'Hello', name: undefined };
+     *
+     *   // default "forgiving" mode

+     *   expect(exp(context)).toEqual('Hello !');

+     *   expect(exp(context)).toBeUndefined();
+     *   context.name = 'Angular';
+     *   expect(exp(context)).toEqual('Hello Angular!');
+     * ```
+     *
+     * `allOrNothing` is useful for interpolating URLs. `ngSrc` and `ngSrcset` use this behavior.
+     *
+     * #### Escaped Interpolation
+     * $interpolate provides a mechanism for escaping interpolation markers. Start and end markers
+     * can be escaped by preceding each of their characters with a REVERSE SOLIDUS U+005C (backslash).
+     * It will be rendered as a regular start/end marker, and will not be interpreted as an expression
+     * or binding.
+     *
+     * This enables web-servers to prevent script injection attacks and defacing attacks, to some
+     * degree, while also enabling code examples to work without relying on the
+     * {@link ng.directive:ngNonBindable ngNonBindable} directive.
+     *
+     * **For security purposes, it is strongly encouraged that web servers escape user-supplied data,
+     * replacing angle brackets (&lt;, &gt;) with &amp;lt; and &amp;gt; respectively, and replacing all
+     * interpolation start/end markers with their escaped counterparts.**
+     *
+     * Escaped interpolation markers are only replaced with the actual interpolation markers in rendered
+     * output when the $interpolate service processes the text. So, for HTML elements interpolated
+     * by {@link ng.$compile $compile}, or otherwise interpolated with the `mustHaveExpression` parameter
+     * set to `true`, the interpolated text must contain an unescaped interpolation expression. As such,
+     * this is typically useful only when user-data is used in rendering a template from the server, or
+     * when otherwise untrusted data is used by a directive.
+     *
+     * <example>
+     *  <file name="index.html">
+     *    <div ng-init="username='A user'">
+     *      <p ng-init="apptitle='Escaping demo'">{{apptitle}}: \{\{ username = "defaced value"; \}\}
+     *        </p>
+     *      <p><strong>{{username}}</strong> attempts to inject code which will deface the
+     *        application, but fails to accomplish their task, because the server has correctly
+     *        escaped the interpolation start/end markers with REVERSE SOLIDUS U+005C (backslash)
+     *        characters.</p>
+     *      <p>Instead, the result of the attempted script injection is visible, and can be removed
+     *        from the database by an administrator.</p>
+     *    </div>
+     *  </file>
+     * </example>
+     *
+     * @knownIssue
+     * It is currently not possible for an interpolated expression to contain the interpolation end
+     * symbol. For example, `{{ '}}' }}` will be incorrectly interpreted as `{{ ' }}` + `' }}`, i.e.
+     * an interpolated expression consisting of a single-quote (`'`) and the `' }}` string.
+     *
+     * @knownIssue
+     * All directives and components must use the standard `{{` `}}` interpolation symbols
+     * in their templates. If you change the application interpolation symbols the {@link $compile}
+     * service will attempt to denormalize the standard symbols to the custom symbols.
+     * The denormalization process is not clever enough to know not to replace instances of the standard
+     * symbols where they would not normally be treated as interpolation symbols. For example in the following
+     * code snippet the closing braces of the literal object will get incorrectly denormalized:
+     *
+     * ```
+     * <div data-context='{"context":{"id":3,"type":"page"}}">
+     * ```
+     *
+     * The workaround is to ensure that such instances are separated by whitespace:
+     * ```
+     * <div data-context='{"context":{"id":3,"type":"page"} }">
+     * ```
+     *
+     * See https://github.com/angular/angular.js/pull/14610#issuecomment-219401099 for more information.

+     * @param {string} text The text with markup to interpolate.

+// Sandboxing Angular Expressions
+// ------------------------------
+// Angular expressions are generally considered safe because these expressions only have direct
+// access to `$scope` and locals. However, one can obtain the ability to execute arbitrary JS code by
+// obtaining a reference to native JS functions such as the Function constructor.
+//
+// As an example, consider the following Angular expression:
+//
+//   {}.toString.constructor('alert("evil JS code")')
+//
+// This sandboxing technique is not perfect and doesn't aim to be. The goal is to prevent exploits
+// against the expression language, but not to prevent exploits that were enabled by exposing
+// sensitive JavaScript or browser APIs on Scope. Exposing such objects on a Scope is never a good
+// practice and therefore we are not even trying to protect against interaction with an object
+// explicitly exposed in this way.
+//
+// In general, it is not possible to access a Window object from an angular expression unless a
+// window or some DOM object that has a reference to window is published onto a Scope.
+// Similarly we prevent invocations of function known to be dangerous, as well as assignments to
+// native objects.
+//

+/**
+ * @ngdoc service
+ * @name $q
+ * @requires $rootScope
+ *
+ * @description
+ * A service that helps you run functions asynchronously, and use their return values (or exceptions)
+ * when they are done processing.
+ *
+ * This is an implementation of promises/deferred objects inspired by
+ * [Kris Kowal's Q](https://github.com/kriskowal/q).
+ *
+ * $q can be used in two fashions --- one which is more similar to Kris Kowal's Q or jQuery's Deferred
+ * implementations, and the other which resembles ES6 (ES2015) promises to some degree.
+ *
+ * # $q constructor
+ *
+ * The streamlined ES6 style promise is essentially just using $q as a constructor which takes a `resolver`
+ * function as the first argument. This is similar to the native Promise implementation from ES6,
+ * see [MDN](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Promise).
+ *
+ * While the constructor-style use is supported, not all of the supporting methods from ES6 promises are
+ * available yet.
+ *
+ * It can be used like so:
+ *
+ * ```js
+ *   // for the purpose of this example let's assume that variables `$q` and `okToGreet`
+ *   // are available in the current lexical scope (they could have been injected or passed in).
+ *
+ *   function asyncGreet(name) {
+ *     // perform some asynchronous operation, resolve or reject the promise when appropriate.
+ *     return $q(function(resolve, reject) {
+ *       setTimeout(function() {
+ *         if (okToGreet(name)) {
+ *           resolve('Hello, ' + name + '!');
+ *         } else {
+ *           reject('Greeting ' + name + ' is not allowed.');
+ *         }
+ *       }, 1000);
+ *     });
+ *   }
+ *
+ *   var promise = asyncGreet('Robin Hood');
+ *   promise.then(function(greeting) {
+ *     alert('Success: ' + greeting);
+ *   }, function(reason) {
+ *     alert('Failed: ' + reason);
+ *   });
+ * ```
+ *
+ * Note: progress/notify callbacks are not currently supported via the ES6-style interface.
+ *
+ * Note: unlike ES6 behavior, an exception thrown in the constructor function will NOT implicitly reject the promise.
+ *
+ * However, the more traditional CommonJS-style usage is still available, and documented below.
+ *
+ * [The CommonJS Promise proposal](http://wiki.commonjs.org/wiki/Promises) describes a promise as an
+ * interface for interacting with an object that represents the result of an action that is
+ * performed asynchronously, and may or may not be finished at any given point in time.
+ *
+ * From the perspective of dealing with error handling, deferred and promise APIs are to
+ * asynchronous programming what `try`, `catch` and `throw` keywords are to synchronous programming.
+ *
+ * ```js
+ *   // for the purpose of this example let's assume that variables `$q` and `okToGreet`
+ *   // are available in the current lexical scope (they could have been injected or passed in).
+ *
+ *   function asyncGreet(name) {
+ *     var deferred = $q.defer();
+ *
+ *     setTimeout(function() {
+ *       deferred.notify('About to greet ' + name + '.');
+ *
+ *       if (okToGreet(name)) {
+ *         deferred.resolve('Hello, ' + name + '!');
+ *       } else {
+ *         deferred.reject('Greeting ' + name + ' is not allowed.');
+ *       }
+ *     }, 1000);
+ *
+ *     return deferred.promise;
+ *   }
+ *
+ *   var promise = asyncGreet('Robin Hood');
+ *   promise.then(function(greeting) {
+ *     alert('Success: ' + greeting);
+ *   }, function(reason) {
+ *     alert('Failed: ' + reason);
+ *   }, function(update) {
+ *     alert('Got notification: ' + update);
+ *   });
+ * ```
+ *
+ * At first it might not be obvious why this extra complexity is worth the trouble. The payoff
+ * comes in the way of guarantees that promise and deferred APIs make, see
+ * https://github.com/kriskowal/uncommonjs/blob/master/promises/specification.md.
+ *
+ * Additionally the promise api allows for composition that is very hard to do with the
+ * traditional callback ([CPS](http://en.wikipedia.org/wiki/Continuation-passing_style)) approach.
+ * For more on this please see the [Q documentation](https://github.com/kriskowal/q) especially the
+ * section on serial or parallel joining of promises.
+ *
+ * # The Deferred API
+ *
+ * A new instance of deferred is constructed by calling `$q.defer()`.
+ *
+ * The purpose of the deferred object is to expose the associated Promise instance as well as APIs
+ * that can be used for signaling the successful or unsuccessful completion, as well as the status
+ * of the task.
+ *
+ * **Methods**
+ *
+ * - `resolve(value)` – resolves the derived promise with the `value`. If the value is a rejection
+ *   constructed via `$q.reject`, the promise will be rejected instead.
+ * - `reject(reason)` – rejects the derived promise with the `reason`. This is equivalent to
+ *   resolving it with a rejection constructed via `$q.reject`.
+ * - `notify(value)` - provides updates on the status of the promise's execution. This may be called
+ *   multiple times before the promise is either resolved or rejected.
+ *
+ * **Properties**
+ *
+ * - promise – `{Promise}` – promise object associated with this deferred.
+ *
+ *
+ * # The Promise API
+ *
+ * A new promise instance is created when a deferred instance is created and can be retrieved by
+ * calling `deferred.promise`.
+ *
+ * The purpose of the promise object is to allow for interested parties to get access to the result
+ * of the deferred task when it completes.
+ *
+ * **Methods**
+ *
+ * - `then(successCallback, [errorCallback], [notifyCallback])` – regardless of when the promise was or
+ *   will be resolved or rejected, `then` calls one of the success or error callbacks asynchronously
+ *   as soon as the result is available. The callbacks are called with a single argument: the result
+ *   or rejection reason. Additionally, the notify callback may be called zero or more times to
+ *   provide a progress indication, before the promise is resolved or rejected.
+ *
+ *   This method *returns a new promise* which is resolved or rejected via the return value of the
+ *   `successCallback`, `errorCallback` (unless that value is a promise, in which case it is resolved
+ *   with the value which is resolved in that promise using
+ *   [promise chaining](http://www.html5rocks.com/en/tutorials/es6/promises/#toc-promises-queues)).
+ *   It also notifies via the return value of the `notifyCallback` method. The promise cannot be
+ *   resolved or rejected from the notifyCallback method. The errorCallback and notifyCallback
+ *   arguments are optional.
+ *
+ * - `catch(errorCallback)` – shorthand for `promise.then(null, errorCallback)`
+ *
+ * - `finally(callback, notifyCallback)` – allows you to observe either the fulfillment or rejection of a promise,
+ *   but to do so without modifying the final value. This is useful to release resources or do some
+ *   clean-up that needs to be done whether the promise was rejected or resolved. See the [full
+ *   specification](https://github.com/kriskowal/q/wiki/API-Reference#promisefinallycallback) for
+ *   more information.
+ *
+ * # Chaining promises
+ *
+ * Because calling the `then` method of a promise returns a new derived promise, it is easily
+ * possible to create a chain of promises:
+ *
+ * ```js
+ *   promiseB = promiseA.then(function(result) {
+ *     return result + 1;
+ *   });
+ *
+ *   // promiseB will be resolved immediately after promiseA is resolved and its value
+ *   // will be the result of promiseA incremented by 1
+ * ```
+ *
+ * It is possible to create chains of any length and since a promise can be resolved with another
+ * promise (which will defer its resolution further), it is possible to pause/defer resolution of
+ * the promises at any point in the chain. This makes it possible to implement powerful APIs like
+ * $http's response interceptors.

+ *
+ * # Differences between Kris Kowal's Q and $q
+ *
+ *  There are two main differences:
+ *
+ * - $q is integrated with the {@link ng.$rootScope.Scope} Scope model observation
+ *   mechanism in angular, which means faster propagation of resolution or rejection into your
+ *   models and avoiding unnecessary browser repaints, which would result in flickering UI.
+ * - Q has many more features than $q, but that comes at a cost of bytes. $q is tiny, but contains
+ *   all the important functionality needed for common async tasks.
+ *
+ * # Testing
+ *
+ *  ```js
+ *    it('should simulate promise', inject(function($q, $rootScope) {
+ *      var deferred = $q.defer();
+ *      var promise = deferred.promise;
+ *      var resolvedValue;
+ *
+ *      promise.then(function(value) { resolvedValue = value; });
+ *      expect(resolvedValue).toBeUndefined();
+ *
+ *      // Simulate resolving of promise
+ *      deferred.resolve(123);
+ *      // Note that the 'then' function does not get called synchronously.
+ *      // This is because we want the promise API to always be async, whether or not
+ *      // it got called synchronously or asynchronously.
+ *      expect(resolvedValue).toBeUndefined();
+ *
+ *      // Propagate promise resolution to 'then' functions using $apply().
+ *      $rootScope.$apply();
+ *      expect(resolvedValue).toEqual(123);
+ *    }));
+ *  ```
+ *
+ * @param {function(function, function)} resolver Function which is responsible for resolving or
+ *   rejecting the newly created promise. The first parameter is a function which resolves the

+ * DESIGN NOTES
+ *
+ * The design decisions behind the scope are heavily favored for speed and memory consumption.
+ *
+ * The typical use of scope is to watch the expressions, which most of the time return the same
+ * value as last time so we optimize the operation.
+ *
+ * Closures construction is expensive in terms of speed as well as memory:
+ *   - No closures, instead use prototypical inheritance for API
+ *   - Internal state needs to be stored on scope directly, which means that private state is
+ *     exposed as $$____ properties
+ *
+ * Loop operations are optimized by using while(count--) { ... }
+ *   - This means that in order to keep the same order of execution as addition we have to add
+ *     items to the array at the beginning (unshift) instead of at the end (push)
+ *
+ * Child scopes are created and removed often
+ *   - Using an array would be slow since inserts in the middle are expensive; so we use linked lists
+ *
+ * There are fewer watches than observers. This is why you don't want the observer to be implemented
+ * in the same way as watch. Watch requires return of the initialization function which is expensive
+ * to construct.

+       * Registers a `listener` callback to be executed whenever the `watchExpression` changes.
+       *
+       * - The `watchExpression` is called on every call to {@link ng.$rootScope.Scope#$digest
+       *   $digest()} and should return the value that will be watched. (`watchExpression` should not change
+       *   its value when executed multiple times with the same input because it may be executed multiple
+       *   times by {@link ng.$rootScope.Scope#$digest $digest()}. That is, `watchExpression` should be
+       *   [idempotent](http://en.wikipedia.org/wiki/Idempotence).
+       * - The `listener` is called only when the value from the current `watchExpression` and the
+       *   previous call to `watchExpression` are not equal (with the exception of the initial run,
+       *   see below). Inequality is determined according to reference inequality,
+       *   [strict comparison](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Comparison_Operators)
+       *    via the `!==` Javascript operator, unless `objectEquality == true`
+       *   (see next point)
+       * - When `objectEquality == true`, inequality of the `watchExpression` is determined
+       *   according to the {@link angular.equals} function. To save the value of the object for
+       *   later comparison, the {@link angular.copy} function is used. This therefore means that
+       *   watching complex objects will have adverse memory and performance implications.
+       * - The watch `listener` may change the model, which may trigger other `listener`s to fire.
+       *   This is achieved by rerunning the watchers until no changes are detected. The rerun
+       *   iteration limit is 10 to prevent an infinite loop deadlock.
+       *
+       *
+       * If you want to be notified whenever {@link ng.$rootScope.Scope#$digest $digest} is called,
+       * you can register a `watchExpression` function with no `listener`. (Be prepared for
+       * multiple calls to your `watchExpression` because it will execute multiple times in a
+       * single {@link ng.$rootScope.Scope#$digest $digest} cycle if a change is detected.)
+       *
+       * After a watcher is registered with the scope, the `listener` fn is called asynchronously
+       * (via {@link ng.$rootScope.Scope#$evalAsync $evalAsync}) to initialize the
+       * watcher. In rare cases, this is undesirable because the listener is called when the result
+       * of `watchExpression` didn't change. To detect this scenario within the `listener` fn, you
+       * can compare the `newVal` and `oldVal`. If these two values are identical (`===`) then the
+       * listener was called due to initialization.
+       *
+       *
+       *
+       * # Example
+       * ```js

+       * @kind function
+       *
+       * @description
+       * Processes all of the {@link ng.$rootScope.Scope#$watch watchers} of the current scope and
+       * its children. Because a {@link ng.$rootScope.Scope#$watch watcher}'s listener can change
+       * the model, the `$digest()` keeps calling the {@link ng.$rootScope.Scope#$watch watchers}
+       * until no more listeners are firing. This means that it is possible to get into an infinite
+       * loop. This function will throw `'Maximum iteration limit exceeded.'` if the number of
+       * iterations exceeds 10.
+       *
+       * Usually, you don't call `$digest()` directly in
+       * {@link ng.directive:ngController controllers} or in
+       * {@link ng.$compileProvider#directive directives}.
+       * Instead, you should call {@link ng.$rootScope.Scope#$apply $apply()} (typically from within
+       * a {@link ng.$compileProvider#directive directive}), which will force a `$digest()`.
+       *
+       * If you want to be notified whenever `$digest()` is called,
+       * you can register a `watchExpression` function with
+       * {@link ng.$rootScope.Scope#$watch $watch()} with no `listener`.
+       *
+       * In unit tests, you may need to call `$digest()` to simulate the scope life cycle.
+       *
+       * # Example
+       * ```js
+           var scope = ...;
+           scope.name = 'misko';
+           scope.counter = 0;
+

+       * cycle of {@link ng.$exceptionHandler exception handling},
+       * {@link ng.$rootScope.Scope#$digest executing watches}.

+       *
+       * Scope's `$apply()` method transitions through the following stages:
+       *
+       * 1. The {@link guide/expression expression} is executed using the
+       *    {@link ng.$rootScope.Scope#$eval $eval()} method.
+       * 2. Any exceptions from the execution of the expression are forwarded to the
+       *    {@link ng.$exceptionHandler $exceptionHandler} service.
+       * 3. The {@link ng.$rootScope.Scope#$watch watch} listeners are fired immediately after the
+       *    expression was executed using the {@link ng.$rootScope.Scope#$digest $digest()} method.

+ * `$sceDelegate` is a service that is used by the `$sce` service to provide {@link ng.$sce Strict
+ * Contextual Escaping (SCE)} services to AngularJS.
+ *
+ * Typically, you would configure or override the {@link ng.$sceDelegate $sceDelegate} instead of
+ * the `$sce` service to customize the way Strict Contextual Escaping works in AngularJS.  This is
+ * because, while the `$sce` provides numerous shorthand methods, etc., you really only need to
+ * override 3 core functions (`trustAs`, `getTrusted` and `valueOf`) to replace the way things
+ * work because `$sce` delegates to `$sceDelegate` for these operations.
+ *
+ * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} to configure this service.
+ *
+ * The default instance of `$sceDelegate` should work out of the box with little pain.  While you
+ * can override it completely to change the behavior of `$sce`, the common case would
+ * involve configuring the {@link ng.$sceDelegateProvider $sceDelegateProvider} instead by setting
+ * your own whitelists and blacklists for trusting URLs used for loading AngularJS resources such as
+ * templates.  Refer {@link ng.$sceDelegateProvider#resourceUrlWhitelist
+ * $sceDelegateProvider.resourceUrlWhitelist} and {@link

+ * @description
+ *
+ * `$sce` is a service that provides Strict Contextual Escaping services to AngularJS.
+ *
+ * # Strict Contextual Escaping
+ *
+ * Strict Contextual Escaping (SCE) is a mode in which AngularJS requires bindings in certain
+ * contexts to result in a value that is marked as safe to use for that context.  One example of
+ * such a context is binding arbitrary html controlled by the user via `ng-bind-html`.  We refer
+ * to these contexts as privileged or SCE contexts.
+ *
+ * As of version 1.2, Angular ships with SCE enabled by default.
+ *
+ * Note:  When enabled (the default), IE<11 in quirks mode is not supported.  In this mode, IE<11 allow
+ * one to execute arbitrary javascript by the use of the expression() syntax.  Refer
+ * <http://blogs.msdn.com/b/ie/archive/2008/10/16/ending-expressions.aspx> to learn more about them.
+ * You can ensure your document is in standards mode and not quirks mode by adding `<!doctype html>`
+ * to the top of your HTML document.
+ *
+ * SCE assists in writing code in a way that (a) is secure by default and (b) makes auditing for
+ * security vulnerabilities such as XSS, clickjacking, etc. a lot easier.
+ *
+ * Here's an example of a binding in a privileged context:
+ *
+ * ```
+ * <input ng-model="userHtml" aria-label="User input">
+ * <div ng-bind-html="userHtml"></div>
+ * ```
+ *
+ * Notice that `ng-bind-html` is bound to `userHtml` controlled by the user.  With SCE
+ * disabled, this application allows the user to render arbitrary HTML into the DIV.
+ * In a more realistic example, one may be rendering user comments, blog articles, etc. via
+ * bindings.  (HTML is just one example of a context where rendering user controlled input creates
+ * security vulnerabilities.)
+ *
+ * For the case of HTML, you might use a library, either on the client side, or on the server side,
+ * to sanitize unsafe HTML before binding to the value and rendering it in the document.
+ *
+ * How would you ensure that every place that used these types of bindings was bound to a value that
+ * was sanitized by your library (or returned as safe for rendering by your server?)  How can you
+ * ensure that you didn't accidentally delete the line that sanitized the value, or renamed some
+ * properties/fields and forgot to update the binding to the sanitized value?
+ *
+ * To be secure by default, you want to ensure that any such bindings are disallowed unless you can
+ * determine that something explicitly says it's safe to use a value for binding in that
+ * context.  You can then audit your code (a simple grep would do) to ensure that this is only done
+ * for those values that you can easily tell are safe - because they were received from your server,
+ * sanitized by your library, etc.  You can organize your codebase to help with this - perhaps
+ * allowing only the files in a specific directory to do this.  Ensuring that the internal API
+ * exposed by that code doesn't markup arbitrary values as safe then becomes a more manageable task.
+ *
+ * In the case of AngularJS' SCE service, one uses {@link ng.$sce#trustAs $sce.trustAs}
+ * (and shorthand methods such as {@link ng.$sce#trustAsHtml $sce.trustAsHtml}, etc.) to
+ * obtain values that will be accepted by SCE / privileged contexts.
+ *
+ *
+ * ## How does it work?
+ *
+ * In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted
+ * $sce.getTrusted(context, value)} rather than to the value directly.  Directives use {@link
+ * ng.$sce#parseAs $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs the
+ * {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals.
+ *
+ * As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link
+ * ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}.  Here's the actual code (slightly
+ * simplified):
+ *
+ * ```
+ * var ngBindHtmlDirective = ['$sce', function($sce) {
+ *   return function(scope, element, attr) {
+ *     scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) {
+ *       element.html(value || '');
+ *     });
+ *   };
+ * }];
+ * ```
+ *
+ * ## Impact on loading templates
+ *
+ * This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as
+ * `templateUrl`'s specified by {@link guide/directive directives}.
+ *
+ * By default, Angular only loads templates from the same domain and protocol as the application
+ * document.  This is done by calling {@link ng.$sce#getTrustedResourceUrl
+ * $sce.getTrustedResourceUrl} on the template URL.  To load templates from other domains and/or
+ * protocols, you may either {@link ng.$sceDelegateProvider#resourceUrlWhitelist whitelist
+ * them} or {@link ng.$sce#trustAsResourceUrl wrap it} into a trusted value.
+ *
+ * *Please note*:
+ * The browser's
+ * [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest)
+ * and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/)
+ * policy apply in addition to this and may further restrict whether the template is successfully
+ * loaded.  This means that without the right CORS policy, loading templates from a different domain
+ * won't work on all browsers.  Also, loading templates from `file://` URL does not work on some
+ * browsers.
+ *
+ * ## This feels like too much overhead
+ *
+ * It's important to remember that SCE only applies to interpolation expressions.
+ *
+ * If your expressions are constant literals, they're automatically trusted and you don't need to
+ * call `$sce.trustAs` on them (remember to include the `ngSanitize` module) (e.g.
+ * `<div ng-bind-html="'<b>implicitly trusted</b>'"></div>`) just works.
+ *
+ * Additionally, `a[href]` and `img[src]` automatically sanitize their URLs and do not pass them
+ * through {@link ng.$sce#getTrusted $sce.getTrusted}.  SCE doesn't play a role here.
+ *
+ * The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load
+ * templates in `ng-include` from your application's domain without having to even know about SCE.
+ * It blocks loading templates from other domains or loading templates over http from an https
+ * served document.  You can change these by setting your own custom {@link
+ * ng.$sceDelegateProvider#resourceUrlWhitelist whitelists} and {@link
+ * ng.$sceDelegateProvider#resourceUrlBlacklist blacklists} for matching such URLs.
+ *
+ * This significantly reduces the overhead.  It is far easier to pay the small overhead and have an
+ * application that's secure and can be audited to verify that with much more ease than bolting
+ * security onto an application later.
+ *
+ * <a name="contexts"></a>
+ * ## What trusted context types are supported?
+ *
+ * | Context             | Notes          |
+ * |---------------------|----------------|
+ * | `$sce.HTML`         | For HTML that's safe to source into the application.  The {@link ng.directive:ngBindHtml ngBindHtml} directive uses this context for bindings. If an unsafe value is encountered and the {@link ngSanitize $sanitize} module is present this will sanitize the value instead of throwing an error. |
+ * | `$sce.CSS`          | For CSS that's safe to source into the application.  Currently unused.  Feel free to use it in your own directives. |
+ * | `$sce.URL`          | For URLs that are safe to follow as links.  Currently unused (`<a href=` and `<img src=` sanitize their urls and don't constitute an SCE context. |
+ * | `$sce.RESOURCE_URL` | For URLs that are not only safe to follow as links, but whose contents are also safe to include in your application.  Examples include `ng-include`, `src` / `ngSrc` bindings for tags other than `IMG` (e.g. `IFRAME`, `OBJECT`, etc.)  <br><br>Note that `$sce.RESOURCE_URL` makes a stronger statement about the URL than `$sce.URL` does and therefore contexts requiring values trusted for `$sce.RESOURCE_URL` can be used anywhere that values trusted for `$sce.URL` are required. |
+ * | `$sce.JS`           | For JavaScript that is safe to execute in your application's context.  Currently unused.  Feel free to use it in your own directives. |
+ *
+ * ## Format of items in {@link ng.$sceDelegateProvider#resourceUrlWhitelist resourceUrlWhitelist}/{@link ng.$sceDelegateProvider#resourceUrlBlacklist Blacklist} <a name="resourceUrlPatternItem"></a>
+ *
+ *  Each element in these arrays must be one of the following:
+ *
+ *  - **'self'**
+ *    - The special **string**, `'self'`, can be used to match against all URLs of the **same
+ *      domain** as the application document using the **same protocol**.
+ *  - **String** (except the special value `'self'`)
+ *    - The string is matched against the full *normalized / absolute URL* of the resource
+ *      being tested (substring matches are not good enough.)
+ *    - There are exactly **two wildcard sequences** - `*` and `**`.  All other characters
+ *      match themselves.
+ *    - `*`: matches zero or more occurrences of any character other than one of the following 6
+ *      characters: '`:`', '`/`', '`.`', '`?`', '`&`' and '`;`'.  It's a useful wildcard for use
+ *      in a whitelist.
+ *    - `**`: matches zero or more occurrences of *any* character.  As such, it's not
+ *      appropriate for use in a scheme, domain, etc. as it would match too much.  (e.g.
+ *      http://**.example.com/ would match http://evil.com/?ignore=.example.com/ and that might
+ *      not have been the intention.)  Its usage at the very end of the path is ok.  (e.g.
+ *      http://foo.example.com/templates/**).
+ *  - **RegExp** (*see caveat below*)
+ *    - *Caveat*:  While regular expressions are powerful and offer great flexibility,  their syntax
+ *      (and all the inevitable escaping) makes them *harder to maintain*.  It's easy to
+ *      accidentally introduce a bug when one updates a complex expression (imho, all regexes should
+ *      have good test coverage).  For instance, the use of `.` in the regex is correct only in a
+ *      small number of cases.  A `.` character in the regex used when matching the scheme or a
+ *      subdomain could be matched against a `:` or literal `.` that was likely not intended.   It
+ *      is highly recommended to use the string patterns and only fall back to regular expressions
+ *      as a last resort.
+ *    - The regular expression must be an instance of RegExp (i.e. not a string.)  It is
+ *      matched against the **entire** *normalized / absolute URL* of the resource being tested
+ *      (even when the RegExp did not have the `^` and `$` codes.)  In addition, any flags
+ *      present on the RegExp (such as multiline, global, ignoreCase) are ignored.
+ *    - If you are generating your JavaScript from some other templating engine (not
+ *      recommended, e.g. in issue [#4006](https://github.com/angular/angular.js/issues/4006)),
+ *      remember to escape your regular expression (and be aware that you might need more than
+ *      one level of escaping depending on your templating engine and the way you interpolated
+ *      the value.)  Do make use of your platform's escaping mechanism as it might be good
+ *      enough before coding your own.  E.g. Ruby has
+ *      [Regexp.escape(str)](http://www.ruby-doc.org/core-2.0.0/Regexp.html#method-c-escape)
+ *      and Python has [re.escape](http://docs.python.org/library/re.html#re.escape).
+ *      Javascript lacks a similar built in function for escaping.  Take a look at Google
+ *      Closure library's [goog.string.regExpEscape(s)](
+ *      http://docs.closure-library.googlecode.com/git/closure_goog_string_string.js.source.html#line962).

+ * for little coding overhead.  It will be much harder to take an SCE disabled application and
+ * either secure it on your own or enable SCE at a later stage.  It might make sense to disable SCE
+ * for cases where you have a lot of existing code that was written before SCE was introduced and
+ * you're migrating them a module at a time.
+ *
+ * That said, here's how you can completely disable SCE:
+ *
+ * ```
+ * angular.module('myAppWithSceDisabledmyApp', []).config(function($sceProvider) {
+ *   // Completely disable SCE.  For demonstration purposes only!
+ *   // Do not use in new projects.
+ *   $sceProvider.enabled(false);
+ * });

+  /* Design notes on the default implementation for SCE.
+   *
+   * The API contract for the SCE delegate
+   * -------------------------------------
+   * The SCE delegate object must provide the following 3 methods:
+   *
+   * - trustAs(contextEnum, value)
+   *     This method is used to tell the SCE service that the provided value is OK to use in the
+   *     contexts specified by contextEnum.  It must return an object that will be accepted by
+   *     getTrusted() for a compatible contextEnum and return this value.
+   *
+   * - valueOf(value)
+   *     For values that were not produced by trustAs(), return them as is.  For values that were
+   *     produced by trustAs(), return the corresponding input value to trustAs.  Basically, if
+   *     trustAs is wrapping the given values into some type, this operation unwraps it when given
+   *     such a value.
+   *
+   * - getTrusted(contextEnum, value)
+   *     This function should return the a value that is safe to use in the context specified by
+   *     contextEnum or throw and exception otherwise.
+   *
+   * NOTE: This contract deliberately does NOT state that values returned by trustAs() must be
+   * opaque or wrapped in some holder object.  That happens to be an implementation detail.  For
+   * instance, an implementation could maintain a registry of all trusted objects by context.  In
+   * such a case, trustAs() would return the same object that was passed in.  getTrusted() would
+   * return the same object passed in if it was found in the registry under a compatible context or
+   * throw an exception otherwise.  An implementation might only wrap values some of the time based
+   * on some criteria.  getTrusted() might return a value and not throw an exception for special
+   * constants or objects even if not wrapped.  All such implementations fulfill this contract.
+   *
+   *
+   * A note on the inheritance model for SCE contexts
+   * ------------------------------------------------
+   * I've used inheritance and made RESOURCE_URL wrapped types a subtype of URL wrapped types.  This
+   * is purely an implementation details.
+   *
+   * The contract is simply this:
+   *
+   *     getTrusted($sce.RESOURCE_URL, value) succeeding implies that getTrusted($sce.URL, value)
+   *     will also succeed.
+   *
+   * Inheritance happens to capture this in a natural way.  In some future, we
+   * may not use inheritance anymore.  That is OK because no code outside of
+   * sce.js and sceSpecs.js would need to be aware of this detail.

+ *
+ * Implementation Notes for non-IE browsers
+ * ----------------------------------------
+ * Assigning a URL to the href property of an anchor DOM node, even one attached to the DOM,
+ * results both in the normalizing and parsing of the URL.  Normalizing means that a relative
+ * URL will be resolved into an absolute URL in the context of the application document.
+ * Parsing means that the anchor node's host, hostname, protocol, port, pathname and related
+ * properties are all populated to reflect the normalized URL.  This approach has wide
+ * compatibility - Safari 1+, Mozilla 1+, Opera 7+,e etc.  See
+ * http://www.aptana.com/reference/html/api/HTMLAnchorElement.html
+ *
+ * Implementation Notes for IE
+ * ---------------------------
+ * IE <= 10 normalizes the URL when assigned to the anchor node similar to the other
+ * browsers.  However, the parsed components will not be set if the URL assigned did not specify
+ * them.  (e.g. if you assign a.href = "foo", then a.protocol, a.host, etc. will be empty.)  We
+ * work around that by performing the parsing in a 2nd step by taking a previously normalized
+ * URL (e.g. by assigning to a.href) and assigning it a.href again.  This correctly populates the
+ * properties such as protocol, hostname, port, etc.

+/**
+ * @ngdoc filter
+ * @name filter
+ * @kind function
+ *
+ * @description
+ * Selects a subset of items from `array` and returns it as a new array.
+ *
+ * @param {Array} array The source array.
+ * @param {string|Object|function()} expression The predicate to be used for selecting items from
+ *   `array`.
+ *
+ *   Can be one of:
+ *
+ *   - `string`: The string is used for matching against the contents of the `array`. All strings or
+ *     objects with string properties in `array` that match this string will be returned. This also
+ *     applies to nested object properties.
+ *     The predicate can be negated by prefixing the string with `!`.
+ *
+ *   - `Object`: A pattern object can be used to filter specific properties on objects contained
+ *     by `array`. For example `{name:"M", phone:"1"}` predicate will return an array of items
+ *     which have property `name` containing "M" and property `phone` containing "1". A special
+ *     property name (`$` by default) can be used (e.g. as in `{$: "text"}`) to accept a match
+ *     against any property of the object or its nested object properties. That's equivalent to the
+ *     simple substring match with a `string` as described above. The special property name can be
+ *     overwritten, using the `anyPropertyKey` parameter.
+ *     The predicate can be negated by prefixing the string with `!`.
+ *     For example `{name: "!M"}` predicate will return an array of items which have property `name`
+ *     not containing "M".
+ *
+ *     Note that a named property will match properties on the same level only, while the special
+ *     `$` property will match properties on the same level or deeper. E.g. an array item like
+ *     `{name: {first: 'John', last: 'Doe'}}` will **not** be matched by `{name: 'John'}`, but
+ *     **will** be matched by `{$: 'John'}`.
+ *
+ *   - `function(value, index, array)`: A predicate function can be used to write arbitrary filters.
+ *     The function is called for each element of the array, with the element, its index, and
+ *     the entire array itself as arguments.
+ *
+ *     The final result is an array of those elements that the predicate returned true for.
+ *
+ * @param {function(actual, expected)|true|undefined} comparator Comparator which is used in
+ *     determining if the expected value (from the filter expression) and actual value (from
+ *     the object in the array) should be considered a match.
+ *
+ *   Can be one of:
+ *
+ *   - `function(actual, expected)`:
+ *     The function will be given the object value and the predicate value to compare and
+ *     should return true if both values should be considered equal.
+ *
+ *   - `true`: A shorthand for `function(actual, expected) { return angular.equals(actual, expected)}`.
+ *     This is essentially strict comparison of expected and actual.
+ *
+ *   - `false|undefined`: A short hand for a function which will look for a substring match in case
+ *     insensitive way.
+ *
+ *     Primitive values are converted to strings. Objects are not compared against primitives,
+ *     unless they have a custom `toString` method (e.g. `Date` objects).
+ *
+ * @param {string=} anyPropertyKey The special property name that matches against any property.
+ *     By default `$`.
+ *
+ * @example

+ * @param {string=} format Formatting rules (see Description). If not specified,
+ *    `mediumDate` is used.
+ * @param {string=} timezone Timezone to be used for formatting. It understands UTC/GMT and the
+ *    continental US time zone abbreviations, but for general use, use a time zone offset, for

+/**
+ * @ngdoc filter
+ * @name orderBy
+ * @kind function
+ *
+ * @description
+ * Returns an array containing the items from the specified `collection`, ordered by a `comparator`
+ * function based on the values computed using the `expression` predicate.
+ *
+ * For example, `[{id: 'foo'}, {id: 'bar'}] | orderBy:'id'` would result in
+ * `[{id: 'bar'}, {id: 'foo'}]`.
+ *
+ * The `collection` can be an Array or array-like object (e.g. NodeList, jQuery object, TypedArray,
+ * String, etc).
+ *
+ * The `expression` can be a single predicate, or a list of predicates each serving as a tie-breaker
+ * for the preceeding one. The `expression` is evaluated against each item and the output is used
+ * for comparing with other items.
+ *
+ * You can change the sorting order by setting `reverse` to `true`. By default, items are sorted in
+ * ascending order.
+ *
+ * The comparison is done using the `comparator` function. If none is specified, a default, built-in
+ * comparator is used (see below for details - in a nutshell, it compares numbers numerically and
+ * strings alphabetically).
+ *
+ * ### Under the hood
+ *
+ * Ordering the specified `collection` happens in two phases:
+ *
+ * 1. All items are passed through the predicate (or predicates), and the returned values are saved
+ *    along with their type (`string`, `number` etc). For example, an item `{label: 'foo'}`, passed
+ *    through a predicate that extracts the value of the `label` property, would be transformed to:
+ *    ```
+ *    {
+ *      value: 'foo',
+ *      type: 'string',
+ *      index: ...
+ *    }
+ *    ```
+ * 2. The comparator function is used to sort the items, based on the derived values, types and
+ *    indices.
+ *
+ * If you use a custom comparator, it will be called with pairs of objects of the form
+ * `{value: ..., type: '...', index: ...}` and is expected to return `0` if the objects are equal
+ * (as far as the comparator is concerned), `-1` if the 1st one should be ranked higher than the
+ * second, or `1` otherwise.
+ *
+ * In order to ensure that the sorting will be deterministic across platforms, if none of the
+ * specified predicates can distinguish between two items, `orderBy` will automatically introduce a
+ * dummy predicate that returns the item's index as `value`.
+ * (If you are using a custom comparator, make sure it can handle this predicate as well.)
+ *
+ * Finally, in an attempt to simplify things, if a predicate returns an object as the extracted
+ * value for an item, `orderBy` will try to convert that object to a primitive value, before passing
+ * it to the comparator. The following rules govern the conversion:
+ *
+ * 1. If the object has a `valueOf()` method that returns a primitive, its return value will be
+ *    used instead.<br />
+ *    (If the object has a `valueOf()` method that returns another object, then the returned object
+ *    will be used in subsequent steps.)
+ * 2. If the object has a custom `toString()` method (i.e. not the one inherited from `Object`) that
+ *    returns a primitive, its return value will be used instead.<br />
+ *    (If the object has a `toString()` method that returns another object, then the returned object
+ *    will be used in subsequent steps.)
+ * 3. No conversion; the object itself is used.
+ *
+ * ### The default comparator
+ *
+ * The default, built-in comparator should be sufficient for most usecases. In short, it compares
+ * numbers numerically, strings alphabetically (and case-insensitively), for objects falls back to
+ * using their index in the original collection, and sorts values of different types by type.
+ *
+ * More specifically, it follows these steps to determine the relative order of items:
+ *
+ * 1. If the compared values are of different types, compare the types themselves alphabetically.
+ * 2. If both values are of type `string`, compare them alphabetically in a case- and
+ *    locale-insensitive way.
+ * 3. If both values are objects, compare their indices instead.
+ * 4. Otherwise, return:
+ *    -  `0`, if the values are equal (by strict equality comparison, i.e. using `===`).
+ *    - `-1`, if the 1st value is "less than" the 2nd value (compared using the `<` operator).
+ *    -  `1`, otherwise.
+ *
+ * **Note:** If you notice numbers not being sorted as expected, make sure they are actually being
+ *           saved as numbers and not strings.
+ *
+ * @param {Array|ArrayLike} collection - The collection (array or array-like object) to sort.
+ * @param {(Function|string|Array.<Function|string>)=} expression - A predicate (or list of
+ *    predicates) to be used by the comparator to determine the order of elements.
+ *
+ *    Can be one of:
+ *
+ *    - `Function`: A getter function. This function will be called with each item as argument and
+ *      the return value will be used for sorting.
+ *    - `string`: An Angular expression. This expression will be evaluated against each item and the
+ *      result will be used for sorting. For example, use `'label'` to sort by a property called
+ *      `label` or `'label.substring(0, 3)'` to sort by the first 3 characters of the `label`
+ *      property.<br />
+ *      (The result of a constant expression is interpreted as a property name to be used for
+ *      comparison. For example, use `'"special name"'` (note the extra pair of quotes) to sort by a
+ *      property called `special name`.)<br />
+ *      An expression can be optionally prefixed with `+` or `-` to control the sorting direction,
+ *      ascending or descending. For example, `'+label'` or `'-label'`. If no property is provided,
+ *      (e.g. `'+'` or `'-'`), the collection element itself is used in comparisons.
+ *    - `Array`: An array of function and/or string predicates. If a predicate cannot determine the
+ *      relative order of two items, the next predicate is used as a tie-breaker.
+ *
+ * **Note:** If the predicate is missing or empty then it defaults to `'+'`.
+ *
+ * @param {boolean=} reverse - If `true`, reverse the sorting order.
+ * @param {(Function)=} comparator - The comparator function used to determine the relative order of
+ *    value pairs. If omitted, the built-in comparator will be used.
+ *
+ * @returns {Array} - The sorted array.
+ *
+ *
+ * @example
+ * ### Ordering a table with `ngRepeat`
+ *
+ * The example below demonstrates a simple {@link ngRepeat ngRepeat}, where the data is sorted by
+ * age in descending order (expression is set to `'-age'`). The `comparator` is not set, which means
+ * it defaults to the built-in comparator.

+ *
+ * If you have very specific requirements about the way items are sorted, you can pass your own
+ * comparator function. For example, you might need to compare some strings in a locale-sensitive
+ * way. (When specifying a custom comparator, you also need to pass a value for the `reverse`
+ * argument - passing `false` retains the default sorting order, i.e. ascending.)

+ /**
+ * @ngdoc directive
+ * @name form
+ * @restrict E
+ *
+ * @description
+ * Directive that instantiates

+ *
+ * If the `name` attribute is specified, the form controller is published onto the current scope under
+ * this name.
+ *
+ * # Alias: {@link ng.directive:ngForm `ngForm`}
+ *
+ * In Angular, forms can be nested. This means that the outer form is valid when all of the child
+ * forms are valid as well. However, browsers do not allow nesting of `<form>` elements, so
+ * Angular provides the {@link ng.directive:ngForm `ngForm`} directive, which behaves identically to
+ * `form` but can be nested. Nested forms can be useful, for example, if the validity of a sub-group
+ * of controls needs to be determined.
+ *
+ * # CSS classes
+ *  - `ng-valid` is set if the form is valid.
+ *  - `ng-invalid` is set if the form is invalid.
+ *  - `ng-pending` is set if the form is pending.
+ *  - `ng-pristine` is set if the form is pristine.
+ *  - `ng-dirty` is set if the form is dirty.
+ *  - `ng-submitted` is set if the form was submitted.
+ *
+ * Keep in mind that ngAnimate can detect each of these classes when added and removed.
+ *
+ *
+ * # Submitting a form and preventing the default action
+ *
+ * Since the role of forms in client-side Angular applications is different than in classical
+ * roundtrip apps, it is desirable for the browser not to translate the form submission into a full
+ * page reload that sends the data to the server. Instead some javascript logic should be triggered
+ * to handle the form submission in an application-specific way.
+ *
+ * For this reason, Angular prevents the default action (form submission to the server) unless the
+ * `<form>` element has an `action` attribute specified.
+ *
+ * You can use one of the following two ways to specify what javascript method should be called when
+ * a form is submitted:
+ *
+ * - {@link ng.directive:ngSubmit ngSubmit} directive on the form element
+ * - {@link ng.directive:ngClick ngClick} directive on the first
+  *  button or input field of type submit (input[type=submit])
+ *
+ * To prevent double execution of the handler, use only one of the {@link ng.directive:ngSubmit ngSubmit}
+ * or {@link ng.directive:ngClick ngClick} directives.
+ * This is because of the following form submission rules in the HTML specification:
+ *
+ * - If a form has only one input field then hitting enter in this field triggers form submit
+ * (`ngSubmit`)
+ * - if a form has 2+ input fields and no buttons or input[type=submit] then hitting enter
+ * doesn't trigger submit
+ * - if a form has one or more input fields and one or more buttons or input[type=submit] then
+ * hitting enter in any of the input fields will trigger the click handler on the *first* button or
+ * input[type=submit] (`ngClick`) *and* a submit handler on the enclosing form (`ngSubmit`)
+ *
+ * Any pending `ngModelOptions` changes will take place immediately when an enclosing form is
+ * submitted. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`
+ * to have access to the updated model.
+ *
+ * ## Animation Hooks
+ *
+ * Animations in ngForm are triggered when any of the associated CSS classes are added and removed.
+ * These classes are: `.ng-pristine`, `.ng-dirty`, `.ng-invalid` and `.ng-valid` as well as any
+ * other validations that are performed within the form. Animations in ngForm are similar to how
+ * they work in ngClass and animations can be hooked into using CSS transitions, keyframes as well
+ * as JS animations.
+ *
+ * The following example shows a simple way to utilize CSS transitions to style a form element
+ * that has been rendered as invalid after it has been validated:
+ *
+ * <pre>
+ * //be sure to include ngAnimate as a module to hook into more
+ * //advanced animations
+ * .my-form {
+ *   transition:0.5s linear all;
+ *   background: white;
+ * }
+ * .my-form.ng-invalid {
+ *   background: red;
+ *   color:white;
+ * }
+ * </pre>
+ *
+ * @example
+    <example deps="angular-animate.js" animations="true" fixBase="true" module="formExample">
+      <file name="index.html">
+       <script>

+       <style>
+        .my-form {
+          transition:all linear 0.5s;
+          background: transparent;
+        }
+        .my-form.ng-invalid {
+          background: red;

+   * @param {string=} pattern Similar to `ngPattern` except that the attribute value is the actual string
+   *    that contains the regular expression body that will be converted to a regular expression
+   *    as in the ngPattern directive.
+   * @param {string=} ngPattern Sets `pattern` validation error key if the ngModel {@link ngModel.NgModelController#$viewValue $viewValue}
+   *    does not match a RegExp found by evaluating the Angular expression given in the attribute value.
+   *    If the expression evaluates to a RegExp object, then this is used directly.
+   *    If the expression evaluates to a string, then it will be converted to a RegExp
+   *    after wrapping it in `^` and `$` characters. For instance, `"abc"` will be converted to
+   *    `new RegExp('^abc$')`.<br />
+   *    **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to
+   *    start at the index of the last search's match, thus not taking the whole input value into
+   *    account.
+   * @param {string=} ngChange Angular expression to be executed when input changes due to user
+   *    interaction with the input element.
+   * @param {boolean=} [ngTrim=true] If set to false Angular will not automatically trim the input.
+   *    This parameter is ignored for input[type=password] controls, which will never trim the
+   *    input.

+   * @description
+   * Text input with email validation. Sets the `email` validation error key if not a valid email
+   * address.
+   *
+   * <div class="alert alert-warning">
+   * **Note:** `input[email]` uses a regex to validate email addresses that is derived from the regex
+   * used in Chromium. If you need stricter validation (e.g. requiring a top-level domain), you can
+   * use `ng-pattern` or modify the built-in validators (see the {@link guide/forms Forms guide})
+   * </div>
+   *
+   * @param {string} ngModel Assignable angular expression to data-bind to.
+   * @param {string=} name Property name of the form under which the control is published.
+   * @param {string=} required Sets `required` validation error key if the value is not entered.
+   * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
+   *    the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
+   *    `required` when you want to data-bind to the `required` attribute.
+   * @param {number=} ngMinlength Sets `minlength` validation error key if the value is shorter than
+   *    minlength.
+   * @param {number=} ngMaxlength Sets `maxlength` validation error key if the value is longer than
+   *    maxlength. Setting the attribute to a negative or non-numeric value, allows view values of
+   *    any length.
+   * @param {string=} pattern Similar to `ngPattern` except that the attribute value is the actual string
+   *    that contains the regular expression body that will be converted to a regular expression
+   *    as in the ngPattern directive.
+   * @param {string=} ngPattern Sets `pattern` validation error key if the ngModel {@link ngModel.NgModelController#$viewValue $viewValue}
+   *    does not match a RegExp found by evaluating the Angular expression given in the attribute value.
+   *    If the expression evaluates to a RegExp object, then this is used directly.
+   *    If the expression evaluates to a string, then it will be converted to a RegExp
+   *    after wrapping it in `^` and `$` characters. For instance, `"abc"` will be converted to
+   *    `new RegExp('^abc$')`.<br />
+   *    **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to
+   *    start at the index of the last search's match, thus not taking the whole input value into
+   *    account.
+   * @param {string=} ngChange Angular expression to be executed when input changes due to user
+   *    interaction with the input element.

+ *
+ * Typically, you don't use `ngBind` directly, but instead you use the double curly markup like

+ *
+ * It is preferable to use `ngBind` instead of `{{ expression }}` if a template is momentarily
+ * displayed by the browser in its raw state before Angular compiles it. Since `ngBind` is an
+ * element attribute, it makes the bindings invisible to the user while the page is loading.
+ *
+ * An alternative solution to this problem would be using the

+/**
+ * @ngdoc directive
+ * @name ngClass
+ * @restrict AC
+ *
+ * @description
+ * The `ngClass` directive allows you to dynamically set CSS classes on an HTML element by databinding
+ * an expression that represents all classes to be added.
+ *
+ * The directive operates in three different ways, depending on which of three types the expression
+ * evaluates to:
+ *
+ * 1. If the expression evaluates to a string, the string should be one or more space-delimited class
+ * names.
+ *
+ * 2. If the expression evaluates to an object, then for each key-value pair of the
+ * object with a truthy value the corresponding key is used as a class name.
+ *
+ * 3. If the expression evaluates to an array, each element of the array should either be a string as in
+ * type 1 or an object as in type 2. This means that you can mix strings and objects together in an array
+ * to give you more control over what CSS classes appear. See the code below for an example of this.
+ *
+ *
+ * The directive won't add duplicate classes if a particular class was already set.
+ *
+ * When the expression changes, the previously added classes are removed and only then are the
+ * new classes added.
+ *
+ * @knownIssue
+ * You should not use {@link guide/interpolation interpolation} in the value of the `class`
+ * attribute, when using the `ngClass` directive on the same element.
+ * See {@link guide/interpolation#known-issues here} for more info.
+ *
+ * @animations
+ * | Animation                        | Occurs                              |
+ * |----------------------------------|-------------------------------------|
+ * | {@link ng.$animate#addClass addClass}       | just before the class is applied to the element   |
+ * | {@link ng.$animate#removeClass removeClass} | just before the class is removed from the element |
+ *
+ * @element ANY
+ * @param {expression} ngClass {@link guide/expression Expression} to eval. The result
+ *   of the evaluation can be a string representing space delimited class
+ *   names, an array, or a map of class names to boolean values. In the case of a map, the
+ *   names of the properties whose values are truthy will be added as css classes to the
+ *   element.
+ *
+ * @example Example that demonstrates basic bindings via ngClass directive.

+ *
+ * @description
+ * The `ngCloak` directive is used to prevent the Angular html template from being briefly
+ * displayed by the browser in its raw (uncompiled) form while your application is loading. Use this
+ * directive to avoid the undesirable flicker effect caused by the html template display.
+ *
+ * The directive can be applied to the `<body>` element, but the preferred usage is to apply
+ * multiple `ngCloak` directives to small portions of the page to permit progressive rendering
+ * of the browser view.
+ *
+ * `ngCloak` works in cooperation with the following css rule embedded within `angular.js` and
+ * `angular.min.js`.
+ * For CSP mode please add `angular-csp.css` to your html file (see {@link ng.directive:ngCsp ngCsp}).
+ *
+ * ```css
+ * [ng\:cloak], [ng-cloak], [data-ng-cloak], [x-ng-cloak], .ng-cloak, .x-ng-cloak {
+ *   display: none !important;
+ * }
+ * ```
+ *
+ * When this css rule is loaded by the browser, all html elements (including their children) that
+ * are tagged with the `ngCloak` directive are hidden. When Angular encounters this directive
+ * during the compilation of the template it deletes the `ngCloak` element attribute, making
+ * the compiled element visible.
+ *
+ * For the best result, the `angular.js` script must be loaded in the head section of the html

+/**
+ * @ngdoc directive
+ * @name ngController
+ *
+ * @description
+ * The `ngController` directive attaches a controller class to the view. This is a key aspect of how angular
+ * supports the principles behind the Model-View-Controller design pattern.
+ *
+ * MVC components in angular:
+ *
+ * * Model — Models are the properties of a scope; scopes are attached to the DOM where scope properties
+ *   are accessed through bindings.
+ * * View — The template (HTML with data bindings) that is rendered into the View.
+ * * Controller — The `ngController` directive specifies a Controller class; the class contains business
+ *   logic behind the application to decorate the scope with functions and values
+ *
+ * Note that you can also attach controllers to the DOM by declaring it in a route definition
+ * via the {@link ngRoute.$route $route} service. A common mistake is to declare the controller
+ * again using `ng-controller` in the template itself.  This will cause the controller to be attached
+ * and executed twice.
+ *
+ * @element ANY
+ * @scope
+ * @priority 500
+ * @param {expression} ngController Name of a constructor function registered with the current
+ * {@link ng.$controllerProvider $controllerProvider} or an {@link guide/expression expression}
+ * that on the current scope evaluates to a constructor function.
+ *
+ * The controller instance can be published into a scope property by specifying
+ * `ng-controller="as propertyName"`.
+ *
+ * If the current `$controllerProvider` is configured to use globals (via
+ * {@link ng.$controllerProvider#allowGlobals `$controllerProvider.allowGlobals()` }), this may
+ * also be the name of a globally accessible constructor function (not recommended).
+ *
+ * @example
+ * Here is a simple form for editing user contact information. Adding, removing, clearing, and
+ * greeting are methods declared on the controller (see source tab). These methods can
+ * easily be called from the angular markup. Any changes to the data are automatically reflected
+ * in the View without the need for a manual update.
+ *
+ * Two different declaration styles are included below:
+ *
+ * * one binds methods and properties directly onto the controller using `this`:
+ * `ng-controller="SettingsController1 as settings"`
+ * * one injects `$scope` into the controller:
+ * `ng-controller="SettingsController2"`
+ *
+ * The second option is more common in the Angular community, and is generally used in boilerplates
+ * and in this guide. However, there are advantages to binding properties directly to the controller
+ * and avoiding scope.
+ *
+ * * Using `controller as` makes it obvious which controller you are accessing in the template when
+ * multiple controllers apply to an element.
+ * * If you are writing your controllers as classes you have easier access to the properties and
+ * methods, which will appear on the scope, from inside the controller code.
+ * * Since there is always a `.` in the bindings, you don't have to worry about prototypal
+ * inheritance masking primitives.
+ *
+ * This example demonstrates the `controller as` syntax.

+ * @ngdoc directive
+ * @name ngCsp
+ *
+ * @element html
+ * @description
+ *
+ * Angular has some features that can break certain
+ * [CSP (Content Security Policy)](https://developer.mozilla.org/en/Security/CSP) rules.
+ *
+ * If you intend to implement these rules then you must tell Angular not to use these features.
+ *
+ * This is necessary when developing things like Google Chrome Extensions or Universal Windows Apps.
+ *
+ *
+ * The following rules affect Angular:
+ *
+ * * `unsafe-eval`: this rule forbids apps to use `eval` or `Function(string)` generated functions
+ * (among other things). Angular makes use of this in the {@link $parse} service to provide a 30%
+ * increase in the speed of evaluating Angular expressions.
+ *
+ * * `unsafe-inline`: this rule forbids apps from inject custom styles into the document. Angular
+ * makes use of this to include some CSS rules (e.g. {@link ngCloak} and {@link ngHide}).
+ * To make these directives work when a CSP rule is blocking inline styles, you must link to the
+ * `angular-csp.css` in your HTML manually.
+ *
+ * If you do not provide `ngCsp` then Angular tries to autodetect if CSP is blocking unsafe-eval
+ * and automatically deactivates this feature in the {@link $parse} service. This autodetection,
+ * however, triggers a CSP error to be logged in the console:
+ *
+ * ```
+ * Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of
+ * script in the following Content Security Policy directive: "default-src 'self'". Note that
+ * 'script-src' was not explicitly set, so 'default-src' is used as a fallback.
+ * ```
+ *
+ * This error is harmless but annoying. To prevent the error from showing up, put the `ngCsp`
+ * directive on an element of the HTML document that appears before the `<script>` tag that loads
+ * the `angular.js` file.
+ *
+ * *Note: This directive is only available in the `ng-csp` and `data-ng-csp` attribute form.*
+ *
+ * You can specify which of the CSP related Angular features should be deactivated by providing
+ * a value for the `ng-csp` attribute. The options are as follows:
+ *
+ * * no-inline-style: this stops Angular from injecting CSS styles into the DOM
+ *
+ * * no-unsafe-eval: this stops Angular from optimizing $parse with unsafe eval of strings
+ *
+ * You can use these values in the following combinations:
+ *
+ *
+ * * No declaration means that Angular will assume that you can do inline styles, but it will do
+ * a runtime check for unsafe-eval. E.g. `<body>`. This is backwardly compatible with previous versions
+ * of Angular.
+ *
+ * * A simple `ng-csp` (or `data-ng-csp`) attribute will tell Angular to deactivate both inline
+ * styles and unsafe eval. E.g. `<body ng-csp>`. This is backwardly compatible with previous versions
+ * of Angular.
+ *
+ * * Specifying only `no-unsafe-eval` tells Angular that we must not use eval, but that we can inject
+ * inline styles. E.g. `<body ng-csp="no-unsafe-eval">`.
+ *
+ * * Specifying only `no-inline-style` tells Angular that we must not inject styles, but that we can
+ * run eval - no automatic check for unsafe eval will occur. E.g. `<body ng-csp="no-inline-style">`
+ *
+ * * Specifying both `no-unsafe-eval` and `no-inline-style` tells Angular that we must not inject
+ * styles nor use eval, which is the same as an empty: ng-csp.
+ * E.g.`<body ng-csp="no-inline-style;no-unsafe-eval">`
+ *
+ * @example
+ * This example shows how to apply the `ngCsp` directive to the `html` tag.
+   ```html
+     <!doctype html>
+     <html ng-app ng-csp>
+     ...
+     ...

+  * @example

+ * @name ngIf
+ * @restrict A
+ * @multiElement
+ *
+ * @description
+ * The `ngIf` directive removes or recreates a portion of the DOM tree based on an
+ * {expression}. If the expression assigned to `ngIf` evaluates to a false
+ * value then the element is removed from the DOM, otherwise a clone of the
+ * element is reinserted into the DOM.
+ *
+ * `ngIf` differs from `ngShow` and `ngHide` in that `ngIf` completely removes and recreates the
+ * element in the DOM rather than changing its visibility via the `display` css property.  A common
+ * case when this difference is significant is when using css selectors that rely on an element's
+ * position within the DOM, such as the `:first-child` or `:last-child` pseudo-classes.
+ *
+ * Note that when an element is removed using `ngIf` its scope is destroyed and a new scope
+ * is created when the element is restored.  The scope created within `ngIf` inherits from
+ * its parent scope using
+ * [prototypal inheritance](https://github.com/angular/angular.js/wiki/Understanding-Scopes#javascript-prototypal-inheritance).
+ * An important implication of this is if `ngModel` is used within `ngIf` to bind to
+ * a javascript primitive defined in the parent scope. In this case any modifications made to the
+ * variable within the child scope will override (hide) the value in the parent scope.
+ *
+ * Also, `ngIf` recreates elements using their compiled state. An example of this behavior
+ * is if an element's class attribute is directly modified after it's compiled, using something like
+ * jQuery's `.addClass()` method, and the element is later removed. When `ngIf` recreates the element
+ * the added class will be lost because the original compiled state is used to regenerate the element.
+ *
+ * Additionally, you can provide animations via the `ngAnimate` module to animate the `enter`
+ * and `leave` effects.
+ *
+ * @animations
+ * | Animation                        | Occurs                               |

+ * | {@link ng.$animate#enter enter}  | just after the `ngIf` contents change and a new DOM element is created and injected into the `ngIf` container |
+ * | {@link ng.$animate#leave leave}  | just before the `ngIf` contents are removed from the DOM |
+ *
+ * @element ANY
+ * @scope
+ * @priority 600
+ * @param {expression} ngIf If the {@link guide/expression expression} is falsy then
+ *     the element is removed from the DOM tree. If it is truthy a copy of the compiled
+ *     element is added to the DOM tree.

+ * @ngdoc directive

+ * @restrict ECA
+ *
+ * @description
+ * Fetches, compiles and includes an external HTML fragment.
+ *
+ * By default, the template URL is restricted to the same domain and protocol as the
+ * application document. This is done by calling {@link $sce#getTrustedResourceUrl
+ * $sce.getTrustedResourceUrl} on it. To load templates from other domains or protocols
+ * you may either {@link ng.$sceDelegateProvider#resourceUrlWhitelist whitelist them} or
+ * {@link $sce#trustAsResourceUrl wrap them} as trusted values. Refer to Angular's {@link
+ * ng.$sce Strict Contextual Escaping}.
+ *
+ * In addition, the browser's
+ * [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest)
+ * and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/)
+ * policy may further restrict whether the template is successfully loaded.
+ * For example, `ngInclude` won't work for cross-domain requests on all browsers and for `file://`
+ * access on some browsers.
+ *
+ * @animations
+ * | Animation                        | Occurs                              |
+ * |----------------------------------|-------------------------------------|
+ * | {@link ng.$animate#enter enter}  | when the expression changes, on the new include |
+ * | {@link ng.$animate#leave leave}  | when the expression changes, on the old include |
+ *
+ * The enter and leave animation occur concurrently.
+ *
+ * @scope
+ * @priority 400
+ *
+ * @param {string} ngInclude|src angular expression evaluating to URL. If the source is a string constant,
+ *                 make sure you wrap it in **single** quotes, e.g. `src="'myPartialTemplate.html'"`.
+ * @param {string=} onload Expression to evaluate when a new partial is loaded.
+ *                  <div class="alert alert-warning">
+ *                  **Note:** When using onload on SVG elements in IE11, the browser will try to call
+ *                  a function with the name on the window element, which will usually throw a
+ *                  "function is undefined" error. To fix this, you can instead use `data-onload` or a
+ *                  different form that {@link guide/directive#normalization matches} `onload`.
+ *                  </div>
+   *
+ * @param {string=} autoscroll Whether `ngInclude` should call {@link ng.$anchorScroll
+ *                  $anchorScroll} to scroll the viewport after the content is loaded.
+ *
+ *                  - If the attribute is not set, disable scrolling.
+ *                  - If the attribute is set without value, enable scrolling.
+ *                  - Otherwise enable scrolling only if the expression evaluates to truthy value.

+ * delimiter as the value of the `ngList` attribute - for example, `ng-list=" | "`.
+ *
+ * The behaviour of the directive is affected by the use of the `ngTrim` attribute.
+ * * If `ngTrim` is set to `"false"` then whitespace around both the separator and each
+ *   list item is respected. This implies that the user of the directive is responsible for
+ *   dealing with whitespace but also allows you to use whitespace as a delimiter, such as a
+ *   tab or newline character.
+ * * Otherwise whitespace around the delimiter is ignored when splitting (although it is respected
+ *   when joining the list items back together) and whitespace around each list item is stripped
+ *   before it is added to the model.

+ *      provided with the model value as an argument and must return a true or false value depending
+ *      on the response of that validation.

+ *      is delivered then the validation status will be set to true when fulfilled and false when rejected.
+ *      When the asynchronous validators are triggered, each of the validators will run in parallel and the model

+ * Please note that if $http is used then it is important that the server returns a success HTTP response code
+ * in order to fulfill the validation and a status level of `4xx` in order to reject the validation.

+ *
+ * `NgModelController` provides API for the {@link ngModel `ngModel`} directive.
+ * The controller contains services for data-binding, validation, CSS updates, and value formatting
+ * and parsing. It purposefully does not contain any logic which deals with DOM rendering or
+ * listening to DOM events.
+ * Such DOM related logic should be provided by other directives which make use of
+ * `NgModelController` for data-binding to control elements.
+ * Angular provides this DOM logic for most {@link input `input`} elements.
+ * At the end of this page you can find a {@link ngModel.NgModelController#custom-control-example
+ * custom control example} that uses `ngModelController` to bind to `contenteditable` elements.
+ *
+ * @example
+ * ### Custom Control Example
+ * This example shows how to use `NgModelController` with a custom control to achieve
+ * data-binding. Notice how different directives (`contenteditable`, `ng-model`, and `required`)
+ * collaborate together to achieve the desired result.
+ *
+ * `contenteditable` is an HTML5 attribute, which tells the browser to let the element
+ * contents be edited in place by the user.
+ *
+ * We are using the {@link ng.service:$sce $sce} service here and include the {@link ngSanitize $sanitize}
+ * module to automatically remove "bad" content like inline event listener (e.g. `<span onclick="...">`).
+ * However, as we are using `$sce` the model can still decide to provide unsafe content if it marks
+ * that content using the `$sce` service.
+ *
+ * <example name="NgModelController" module="customControl" deps="angular-sanitize.js">
+    <file name="style.css">
+      [contenteditable] {
+        border: 1px solid black;

+        min-height: 20px;
+      }
+

+        border: 1px solid red;

+   * It is also possible that you run into difficulties if you try to update the ngModel's `$modelValue`
+   * programmatically before these debounced/future events have resolved/occurred, because Angular's
+   * dirty checking mechanism is not able to tell whether the model has actually changed or not.
+   *
+   * The `$rollbackViewValue()` method should be called before programmatically changing the model of an
+   * input which may have such events pending. This is important in order to make sure that the
+   * input field will be updated with the new model value and any pending operations are cancelled.

+   * directive calls it when the value of the input changes and {@link ng.directive:select select}
+   * calls it when an option is selected.
+   *
+   * When `$setViewValue` is called, the new `value` will be staged for committing through the `$parsers`
+   * and `$validators` pipelines. If there are no special {@link ngModelOptions} specified then the staged
+   * value sent directly for processing, finally to be applied to `$modelValue` and then the
+   * **expression** specified in the `ng-model` attribute. Lastly, all the registered change listeners,
+   * in the `$viewChangeListeners` list, are called.
+   *
+   * In case the {@link ng.directive:ngModelOptions ngModelOptions} directive is used with `updateOn`
+   * and the `default` trigger is not listed, all those actions will remain pending until one of the
+   * `updateOn` events is triggered on the DOM element.
+   * All these actions will be debounced if the {@link ng.directive:ngModelOptions ngModelOptions}
+   * directive is used with a custom debounce for this particular event.
+   * Note that a `$digest` is only triggered once the `updateOn` events are fired, or if `debounce`
+   * is specified, once the timer runs out.
+   *
+   * When used with standard inputs, the view value will always be a string (which is in some cases
+   * parsed into another type, such as a `Date` object for `input[date]`.)
+   * However, custom controls might also pass objects to this method. In this case, we should make
+   * a copy of the object before passing it to `$setViewValue`. This is because `ngModel` does not
+   * perform a deep watch of objects, it only looks for a change of identity. If you only change
+   * the property of the object then ngModel will not realize that the object has changed and
+   * will not invoke the `$parsers` and `$validators` pipelines. For this reason, you should
+   * not change properties of the copy once it has been passed to `$setViewValue`.
+   * Otherwise you may cause the model value on the scope to change incorrectly.
+   *
+   * <div class="alert alert-info">
+   * In any case, the value passed to the method should always reflect the current value
+   * of the control. For example, if you are calling `$setViewValue` for an input element,
+   * you should pass the input DOM value. Otherwise, the control and the scope model become
+   * out of sync. It's also important to note that `$setViewValue` does not call `$render` or change
+   * the control's DOM value in any way. If we want to change the control's DOM value
+   * programmatically, we should update the `ngModel` scope expression. Its new value will be

+ * @ngdoc directive
+ * @name ngModel
+ *
+ * @element input
+ * @priority 1
+ *
+ * @description
+ * The `ngModel` directive binds an `input`,`select`, `textarea` (or custom form control) to a
+ * property on the scope using {@link ngModel.NgModelController NgModelController},
+ * which is created and exposed by this directive.
+ *
+ * `ngModel` is responsible for:
+ *
+ * - Binding the view into the model, which other directives such as `input`, `textarea` or `select`
+ *   require.
+ * - Providing validation behavior (i.e. required, number, email, url).
+ * - Keeping the state of the control (valid/invalid, dirty/pristine, touched/untouched, validation errors).
+ * - Setting related css classes on the element (`ng-valid`, `ng-invalid`, `ng-dirty`, `ng-pristine`, `ng-touched`,
+ *   `ng-untouched`, `ng-empty`, `ng-not-empty`) including animations.
+ * - Registering the control with its parent {@link ng.directive:form form}.
+ *
+ * Note: `ngModel` will try to bind to the property given by evaluating the expression on the
+ * current scope. If the property doesn't already exist on this scope, it will be created
+ * implicitly and added to the scope.
+ *
+ * For best practices on using `ngModel`, see:
+ *
+ *  - [Understanding Scopes](https://github.com/angular/angular.js/wiki/Understanding-Scopes)
+ *
+ * For basic examples, how to use `ngModel`, see:
+ *
+ *  - {@link ng.directive:input input}
+ *    - {@link input[text] text}
+ *    - {@link input[checkbox] checkbox}
+ *    - {@link input[radio] radio}
+ *    - {@link input[number] number}
+ *    - {@link input[email] email}
+ *    - {@link input[url] url}
+ *    - {@link input[date] date}
+ *    - {@link input[datetime-local] datetime-local}
+ *    - {@link input[time] time}
+ *    - {@link input[month] month}
+ *    - {@link input[week] week}
+ *  - {@link ng.directive:select select}
+ *  - {@link ng.directive:textarea textarea}
+ *
+ * # Complex Models (objects or collections)
+ *
+ * By default, `ngModel` watches the model by reference, not value. This is important to know when
+ * binding inputs to models that are objects (e.g. `Date`) or collections (e.g. arrays). If only properties of the
+ * object or collection change, `ngModel` will not be notified and so the input will not be  re-rendered.
+ *
+ * The model must be assigned an entirely new object or collection before a re-rendering will occur.
+ *
+ * Some directives have options that will cause them to use a custom `$watchCollection` on the model expression
+ * - for example, `ngOptions` will do so when a `track by` clause is included in the comprehension expression or
+ * if the select is given the `multiple` attribute.
+ *
+ * The `$watchCollection()` method only does a shallow comparison, meaning that changing properties deeper than the
+ * first level of the object (or only changing the properties of an item in the collection if it's an array) will still
+ * not trigger a re-rendering of the model.
+ *
+ * # CSS classes
+ * The following CSS classes are added and removed on the associated input/select/textarea element
+ * depending on the validity of the model.
+ *
+ *  - `ng-valid`: the model is valid
+ *  - `ng-invalid`: the model is invalid
+ *  - `ng-valid-[key]`: for each valid key added by `$setValidity`
+ *  - `ng-invalid-[key]`: for each invalid key added by `$setValidity`
+ *  - `ng-pristine`: the control hasn't been interacted with yet
+ *  - `ng-dirty`: the control has been interacted with
+ *  - `ng-touched`: the control has been blurred
+ *  - `ng-untouched`: the control hasn't been blurred
+ *  - `ng-pending`: any `$asyncValidators` are unfulfilled
+ *  - `ng-empty`: the view does not contain a value or the value is deemed "empty", as defined
+ *     by the {@link ngModel.NgModelController#$isEmpty} method
+ *  - `ng-not-empty`: the view contains a non-empty value
+ *
+ * Keep in mind that ngAnimate can detect each of these classes when added and removed.
+ *
+ * ## Animation Hooks
+ *
+ * Animations within models are triggered when any of the associated CSS classes are added and removed
+ * on the input element which is attached to the model. These classes include: `.ng-pristine`, `.ng-dirty`,
+ * `.ng-invalid` and `.ng-valid` as well as any other validations that are performed on the model itself.
+ * The animations that are triggered within ngModel are similar to how they work in ngClass and
+ * animations can be hooked into using CSS transitions, keyframes as well as JS animations.
+ *
+ * The following example shows a simple way to utilize CSS transitions to style an input element
+ * that has been rendered as invalid after it has been validated:
+ *
+ * <pre>
+ * //be sure to include ngAnimate as a module to hook into more
+ * //advanced animations
+ * .my-input {
+ *   transition:0.5s linear all;
+ *   background: white;
+ * }
+ * .my-input.ng-invalid {
+ *   background: red;
+ *   color:white;
+ * }
+ * </pre>
+ *
+ * @example
+ * <example deps="angular-animate.js" animations="true" fixBase="true" module="inputExample">
+     <file name="index.html">
+       <script>
+        angular.module('inputExample', [])
+          .controller('ExampleController', ['$scope', function($scope) {
+            $scope.val = '1';
+          }]);
+       </script>
+       <style>
+         .my-input {
+           transition:all linear 0.5s;

+           color:white;
+           background: red;
+         }
+       </style>
+       <p id="inputDescription">
+        Update input to see transitions when valid/invalid.
+        Integer is a valid value.
+       </p>
+       <form name="testForm" ng-controller="ExampleController">

+ *
+ * ## Binding to a getter/setter
+ *
+ * Sometimes it's helpful to bind `ngModel` to a getter/setter function.  A getter/setter is a
+ * function that returns a representation of the model when called with zero arguments, and sets
+ * the internal state of a model when called with an argument. It's sometimes useful to use this
+ * for models that have an internal representation that's different from what the model exposes
+ * to the view.
+ *
+ * <div class="alert alert-success">
+ * **Best Practice:** It's best to keep getters fast because Angular is likely to call them more
+ * frequently than other parts of your code.
+ * </div>
+ *
+ * You use this behavior by adding `ng-model-options="{ getterSetter: true }"` to an element that
+ * has `ng-model` attached to it. You can also add `ng-model-options="{ getterSetter: true }"` to
+ * a `<form>`, which will enable this behavior for all `<input>`s within it. See
+ * {@link ng.directive:ngModelOptions `ngModelOptions`} for more.
+ *
+ * The following example shows how to use `ngModel` with a getter/setter:
+ *
+ * @example
+ * <example name="ngModel-getter-setter" module="getterSetterExample">
+     <file name="index.html">
+       <div ng-controller="ExampleController">
+         <form name="userForm">
+           <label>Name:
+             <input type="text" name="userName"
+                    ng-model="user.name"
+                    ng-model-options="{ getterSetter: true }" />
+           </label>
+         </form>
+         <pre>user.name = <span ng-bind="user.name()"></span></pre>
+       </div>
+     </file>
+     <file name="app.js">
+       angular.module('getterSetterExample', [])
+         .controller('ExampleController', ['$scope', function($scope) {
+           var _name = 'Brian';
+           $scope.user = {
+             name: function(newName) {
+              // Note that newName can be undefined for two reasons:
+              // 1. Because it is called as a getter and thus called with no arguments
+              // 2. Because the property should actually be set to undefined. This happens e.g. if the
+              //    input is invalid
+              return arguments.length ? (_name = newName) : _name;

+/**
+ * @ngdoc directive
+ * @name ngModelOptions
+ *
+ * @description
+ * Allows tuning how model updates are done. Using `ngModelOptions` you can specify a custom list of
+ * events that will trigger a model update and/or a debouncing delay so that the actual update only
+ * takes place when a timer expires; this timer will be reset after another change takes place.
+ *
+ * Given the nature of `ngModelOptions`, the value displayed inside input fields in the view might
+ * be different from the value in the actual model. This means that if you update the model you
+ * should also invoke {@link ngModel.NgModelController `$rollbackViewValue`} on the relevant input field in
+ * order to make sure it is synchronized with the model and that any debounced action is canceled.
+ *
+ * The easiest way to reference the control's {@link ngModel.NgModelController `$rollbackViewValue`}
+ * method is by making sure the input is placed inside a form that has a `name` attribute. This is
+ * important because `form` controllers are published to the related scope under the name in their
+ * `name` attribute.
+ *
+ * Any pending changes will take place immediately when an enclosing form is submitted via the
+ * `submit` event. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`
+ * to have access to the updated model.
+ *
+ * `ngModelOptions` has an effect on the element it's declared on and its descendants.
+ *
+ * @param {Object} ngModelOptions options to apply to the current model. Valid keys are:
+ *   - `updateOn`: string specifying which event should the input be bound to. You can set several
+ *     events using an space delimited list. There is a special event called `default` that
+ *     matches the default events belonging of the control.
+ *   - `debounce`: integer value which contains the debounce model update value in milliseconds. A
+ *     value of 0 triggers an immediate update. If an object is supplied instead, you can specify a
+ *     custom value for each event. For example:
+ *     `ng-model-options="{ updateOn: 'default blur', debounce: { 'default': 500, 'blur': 0 } }"`
+ *   - `allowInvalid`: boolean value which indicates that the model can be set with values that did
+ *     not validate correctly instead of the default behavior of setting the model to undefined.
+ *   - `getterSetter`: boolean value which determines whether or not to treat functions bound to
+       `ngModel` as getters/setters.
+ *   - `timezone`: Defines the timezone to be used to read/write the `Date` instance in the model for
+ *     `<input type="date">`, `<input type="time">`, ... . It understands UTC/GMT and the
+ *     continental US time zone abbreviations, but for general use, use a time zone offset, for
+ *     example, `'+0430'` (4 hours, 30 minutes east of the Greenwich meridian)
+ *     If not specified, the timezone of the browser will be used.
+ *
+ * @example
+
+  The following example shows how to override immediate updates. Changes on the inputs within the
+  form will update the model only when the control loses focus (blur event). If `escape` key is
+  pressed while the input field is focused, the value is reset to the value in the current model.

+ * @ngdoc directive
+ * @name ngOptions
+ * @restrict A
+ *
+ * @description
+ *
+ * The `ngOptions` attribute can be used to dynamically generate a list of `<option>`
+ * elements for the `<select>` element using the array or object obtained by evaluating the
+ * `ngOptions` comprehension expression.
+ *
+ * In many cases, `ngRepeat` can be used on `<option>` elements instead of `ngOptions` to achieve a
+ * similar result. However, `ngOptions` provides some benefits such as reducing memory and
+ * increasing speed by not creating a new scope for each repeated instance, as well as providing
+ * more flexibility in how the `<select>`'s model is assigned via the `select` **`as`** part of the
+ * comprehension expression. `ngOptions` should be used when the `<select>` model needs to be bound
+ *  to a non-string value. This is because an option element can only be bound to string values at
+ * present.
+ *
+ * When an item in the `<select>` menu is selected, the array element or object property
+ * represented by the selected option will be bound to the model identified by the `ngModel`
+ * directive.
+ *
+ * Optionally, a single hard-coded `<option>` element, with the value set to an empty string, can
+ * be nested into the `<select>` element. This element will then represent the `null` or "not selected"
+ * option. See example below for demonstration.
+ *
+ * ## Complex Models (objects or collections)
+ *
+ * By default, `ngModel` watches the model by reference, not value. This is important to know when
+ * binding the select to a model that is an object or a collection.
+ *
+ * One issue occurs if you want to preselect an option. For example, if you set
+ * the model to an object that is equal to an object in your collection, `ngOptions` won't be able to set the selection,
+ * because the objects are not identical. So by default, you should always reference the item in your collection
+ * for preselections, e.g.: `$scope.selected = $scope.collection[3]`.
+ *
+ * Another solution is to use a `track by` clause, because then `ngOptions` will track the identity
+ * of the item not by reference, but by the result of the `track by` expression. For example, if your
+ * collection items have an id property, you would `track by item.id`.
+ *
+ * A different issue with objects or collections is that ngModel won't detect if an object property or
+ * a collection item changes. For that reason, `ngOptions` additionally watches the model using
+ * `$watchCollection`, when the expression contains a `track by` clause or the the select has the `multiple` attribute.
+ * This allows ngOptions to trigger a re-rendering of the options even if the actual object/collection
+ * has not changed identity, but only a property on the object or an item in the collection changes.
+ *
+ * Note that `$watchCollection` does a shallow comparison of the properties of the object (or the items in the collection
+ * if the model is an array). This means that changing a property deeper than the first level inside the
+ * object/collection will not trigger a re-rendering.
+ *
+ * ## `select` **`as`**
+ *
+ * Using `select` **`as`** will bind the result of the `select` expression to the model, but
+ * the value of the `<select>` and `<option>` html elements will be either the index (for array data sources)
+ * or property name (for object data sources) of the value within the collection. If a **`track by`** expression
+ * is used, the result of that expression will be set as the value of the `option` and `select` elements.
+ *
+ *
+ * ### `select` **`as`** and **`track by`**
+ *
+ * <div class="alert alert-warning">
+ * Be careful when using `select` **`as`** and **`track by`** in the same expression.
+ * </div>
+ *
+ * Given this array of items on the $scope:
+ *
+ * ```js
+ * $scope.items = [{
+ *   id: 1,
+ *   label: 'aLabel',
+ *   subItem: { name: 'aSubItem' }
+ * }, {
+ *   id: 2,
+ *   label: 'bLabel',
+ *   subItem: { name: 'bSubItem' }
+ * }];
+ * ```
+ *
+ * This will work:
+ *
+ * ```html
+ * <select ng-options="item as item.label for item in items track by item.id" ng-model="selected"></select>
+ * ```
+ * ```js
+ * $scope.selected = $scope.items[0];
+ * ```
+ *
+ * but this will not work:
+ *
+ * ```html
+ * <select ng-options="item.subItem as item.label for item in items track by item.id" ng-model="selected"></select>
+ * ```
+ * ```js
+ * $scope.selected = $scope.items[0].subItem;
+ * ```
+ *
+ * In both examples, the **`track by`** expression is applied successfully to each `item` in the
+ * `items` array. Because the selected option has been set programmatically in the controller, the
+ * **`track by`** expression is also applied to the `ngModel` value. In the first example, the
+ * `ngModel` value is `items[0]` and the **`track by`** expression evaluates to `items[0].id` with
+ * no issue. In the second example, the `ngModel` value is `items[0].subItem` and the **`track by`**
+ * expression evaluates to `items[0].subItem.id` (which is undefined). As a result, the model value
+ * is not matched against any `<option>` and the `<select>` appears as having no selected value.
+ *
+ *
+ * @param {string} ngModel Assignable angular expression to data-bind to.
+ * @param {string=} name Property name of the form under which the control is published.
+ * @param {string=} required The control is considered valid only if value is entered.
+ * @param {string=} ngRequired Adds `required` attribute and `required` validation constraint to
+ *    the element when the ngRequired expression evaluates to true. Use `ngRequired` instead of
+ *    `required` when you want to data-bind to the `required` attribute.
+ * @param {comprehension_expression=} ngOptions in one of the following forms:
+ *
+ *   * for array data sources:
+ *     * `label` **`for`** `value` **`in`** `array`
+ *     * `select` **`as`** `label` **`for`** `value` **`in`** `array`
+ *     * `label` **`group by`** `group` **`for`** `value` **`in`** `array`
+ *     * `label` **`disable when`** `disable` **`for`** `value` **`in`** `array`
+ *     * `label` **`group by`** `group` **`for`** `value` **`in`** `array` **`track by`** `trackexpr`
+ *     * `label` **`disable when`** `disable` **`for`** `value` **`in`** `array` **`track by`** `trackexpr`
+ *     * `label` **`for`** `value` **`in`** `array` | orderBy:`orderexpr` **`track by`** `trackexpr`
+ *        (for including a filter with `track by`)
+ *   * for object data sources:
+ *     * `label` **`for (`**`key` **`,`** `value`**`) in`** `object`
+ *     * `select` **`as`** `label` **`for (`**`key` **`,`** `value`**`) in`** `object`
+ *     * `label` **`group by`** `group` **`for (`**`key`**`,`** `value`**`) in`** `object`
+ *     * `label` **`disable when`** `disable` **`for (`**`key`**`,`** `value`**`) in`** `object`
+ *     * `select` **`as`** `label` **`group by`** `group`
+ *         **`for` `(`**`key`**`,`** `value`**`) in`** `object`
+ *     * `select` **`as`** `label` **`disable when`** `disable`
+ *         **`for` `(`**`key`**`,`** `value`**`) in`** `object`
+ *
+ * Where:
+ *
+ *   * `array` / `object`: an expression which evaluates to an array / object to iterate over.
+ *   * `value`: local variable which will refer to each item in the `array` or each property value
+ *      of `object` during iteration.
+ *   * `key`: local variable which will refer to a property name in `object` during iteration.
+ *   * `label`: The result of this expression will be the label for `<option>` element. The
+ *     `expression` will most likely refer to the `value` variable (e.g. `value.propertyName`).
+ *   * `select`: The result of this expression will be bound to the model of the parent `<select>`
+ *      element. If not specified, `select` expression will default to `value`.
+ *   * `group`: The result of this expression will be used to group options using the `<optgroup>`
+ *      DOM element.
+ *   * `disable`: The result of this expression will be used to disable the rendered `<option>`
+ *      element. Return `true` to disable.
+ *   * `trackexpr`: Used when working with an array of objects. The result of this expression will be
+ *      used to identify the objects in the array. The `trackexpr` will most likely refer to the
+ *     `value` variable (e.g. `value.propertyName`). With this the selection is preserved
+ *      even when the options are recreated (e.g. reloaded from the server).

+/**
+ * @ngdoc directive
+ * @name ngPluralize
+ * @restrict EA
+ *
+ * @description
+ * `ngPluralize` is a directive that displays messages according to en-US localization rules.
+ * These rules are bundled with angular.js, but can be overridden
+ * (see {@link guide/i18n Angular i18n} dev guide). You configure ngPluralize directive
+ * by specifying the mappings between
+ * [plural categories](http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html)
+ * and the strings to be displayed.
+ *
+ * # Plural categories and explicit number rules
+ * There are two
+ * [plural categories](http://unicode.org/repos/cldr-tmp/trunk/diff/supplemental/language_plural_rules.html)
+ * in Angular's default en-US locale: "one" and "other".
+ *
+ * While a plural category may match many numbers (for example, in en-US locale, "other" can match
+ * any number that is not 1), an explicit number rule can only match one number. For example, the
+ * explicit number rule for "3" matches the number 3. There are examples of plural categories
+ * and explicit number rules throughout the rest of this documentation.
+ *
+ * # Configuring ngPluralize
+ * You configure ngPluralize by providing 2 attributes: `count` and `when`.
+ * You can also provide an optional attribute, `offset`.
+ *
+ * The value of the `count` attribute can be either a string or an {@link guide/expression
+ * Angular expression}; these are evaluated on the current scope for its bound value.
+ *
+ * The `when` attribute specifies the mappings between plural categories and the actual
+ * string to be displayed. The value of the attribute should be a JSON object.
+ *
+ * The following example shows how to configure ngPluralize:
+ *
+ * ```html
+ * <ng-pluralize count="personCount"
+                 when="{'0': 'Nobody is viewing.',
+ *                      'one': '1 person is viewing.',
+ *                      'other': '{} people are viewing.'}">
+ * </ng-pluralize>
+ *```
+ *
+ * In the example, `"0: Nobody is viewing."` is an explicit number rule. If you did not
+ * specify this rule, 0 would be matched to the "other" category and "0 people are viewing"
+ * would be shown instead of "Nobody is viewing". You can specify an explicit number rule for
+ * other numbers, for example 12, so that instead of showing "12 people are viewing", you can
+ * show "a dozen people are viewing".
+ *
+ * You can use a set of closed braces (`{}`) as a placeholder for the number that you want substituted
+ * into pluralized strings. In the previous example, Angular will replace `{}` with
+ * <span ng-non-bindable>`{{personCount}}`</span>. The closed braces `{}` is a placeholder
+ * for <span ng-non-bindable>{{numberExpression}}</span>.
+ *
+ * If no rule is defined for a category, then an empty string is displayed and a warning is generated.
+ * Note that some locales define more categories than `one` and `other`. For example, fr-fr defines `few` and `many`.
+ *
+ * # Configuring ngPluralize with offset
+ * The `offset` attribute allows further customization of pluralized text, which can result in
+ * a better user experience. For example, instead of the message "4 people are viewing this document",
+ * you might display "John, Kate and 2 others are viewing this document".
+ * The offset attribute allows you to offset a number by any desired value.
+ * Let's take a look at an example:
+ *
+ * ```html
+ * <ng-pluralize count="personCount" offset=2
+ *               when="{'0': 'Nobody is viewing.',
+ *                      '1': '{{person1}} is viewing.',
+ *                      '2': '{{person1}} and {{person2}} are viewing.',
+ *                      'one': '{{person1}}, {{person2}} and one other person are viewing.',
+ *                      'other': '{{person1}}, {{person2}} and {} other people are viewing.'}">
+ * </ng-pluralize>
+ * ```
+ *
+ * Notice that we are still using two plural categories(one, other), but we added
+ * three explicit number rules 0, 1 and 2.
+ * When one person, perhaps John, views the document, "John is viewing" will be shown.
+ * When three people view the document, no explicit number rule is found, so
+ * an offset of 2 is taken off 3, and Angular uses 1 to decide the plural category.
+ * In this case, plural category 'one' is matched and "John, Mary and one other person are viewing"
+ * is shown.
+ *
+ * Note that when you specify offsets, you must provide explicit number rules for
+ * numbers from 0 up to and including the offset. If you use an offset of 3, for example,
+ * you must provide explicit number rules for 0, 1, 2 and 3. You must also provide plural strings for
+ * plural categories "one" and "other".
+ *
+ * @param {string|expression} count The variable to be bound to.
+ * @param {string} when The mapping between plural category to its corresponding strings.
+ * @param {number=} offset Offset to deduct from the total number.
+ *

+ * @ngdoc directive

+ *
+ * @description
+ * The `ngRepeat` directive instantiates a template once per item from a collection. Each template
+ * instance gets its own scope, where the given loop variable is set to the current collection item,
+ * and `$index` is set to the item index or key.
+ *
+ * Special properties are exposed on the local scope of each template instance, including:
+ *
+ * | Variable  | Type            | Details                                                                     |
+ * |-----------|-----------------|-----------------------------------------------------------------------------|
+ * | `$index`  | {@type number}  | iterator offset of the repeated element (0..length-1)                       |
+ * | `$first`  | {@type boolean} | true if the repeated element is first in the iterator.                      |
+ * | `$middle` | {@type boolean} | true if the repeated element is between the first and last in the iterator. |
+ * | `$last`   | {@type boolean} | true if the repeated element is last in the iterator.                       |
+ * | `$even`   | {@type boolean} | true if the iterator position `$index` is even (otherwise false).           |
+ * | `$odd`    | {@type boolean} | true if the iterator position `$index` is odd (otherwise false).            |
+ *
+ * <div class="alert alert-info">
+ *   Creating aliases for these properties is possible with {@link ng.directive:ngInit `ngInit`}.
+ *   This may be useful when, for instance, nesting ngRepeats.
+ * </div>
+ *
+ *
+ * # Iterating over object properties
+ *
+ * It is possible to get `ngRepeat` to iterate over the properties of an object using the following
+ * syntax:
+ *
+ * ```js
+ * <div ng-repeat="(key, value) in myObj"> ... </div>
+ * ```
+ *
+ * However, there are a limitations compared to array iteration:
+ *
+ * - The JavaScript specification does not define the order of keys
+ *   returned for an object, so Angular relies on the order returned by the browser
+ *   when running `for key in myObj`. Browsers generally follow the strategy of providing
+ *   keys in the order in which they were defined, although there are exceptions when keys are deleted
+ *   and reinstated. See the
+ *   [MDN page on `delete` for more info](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/delete#Cross-browser_notes).
+ *
+ * - `ngRepeat` will silently *ignore* object keys starting with `$`, because
+ *   it's a prefix used by Angular for public (`$`) and private (`$$`) properties.
+ *
+ * - The built-in filters {@link ng.orderBy orderBy} and {@link ng.filter filter} do not work with
+ *   objects, and will throw an error if used with one.
+ *
+ * If you are hitting any of these limitations, the recommended workaround is to convert your object into an array
+ * that is sorted into the order that you prefer before providing it to `ngRepeat`. You could
+ * do this with a filter such as [toArrayFilter](http://ngmodules.org/modules/angular-toArrayFilter)
+ * or implement a `$watch` on the object yourself.
+ *
+ *
+ * # Tracking and Duplicates
+ *
+ * `ngRepeat` uses {@link $rootScope.Scope#$watchCollection $watchCollection} to detect changes in
+ * the collection. When a change happens, ngRepeat then makes the corresponding changes to the DOM:
+ *
+ * * When an item is added, a new instance of the template is added to the DOM.
+ * * When an item is removed, its template instance is removed from the DOM.
+ * * When items are reordered, their respective templates are reordered in the DOM.
+ *
+ * To minimize creation of DOM elements, `ngRepeat` uses a function
+ * to "keep track" of all items in the collection and their corresponding DOM elements.
+ * For example, if an item is added to the collection, ngRepeat will know that all other items
+ * already have DOM elements, and will not re-render them.
+ *
+ * The default tracking function (which tracks items by their identity) does not allow
+ * duplicate items in arrays. This is because when there are duplicates, it is not possible
+ * to maintain a one-to-one mapping between collection items and DOM elements.
+ *
+ * If you do need to repeat duplicate items, you can substitute the default tracking behavior
+ * with your own using the `track by` expression.
+ *
+ * For example, you may track items by the index of each item in the collection, using the
+ * special scope property `$index`:
+ * ```html
+ *    <div ng-repeat="n in [42, 42, 43, 43] track by $index">
+ *      {{n}}
+ *    </div>
+ * ```
+ *
+ * You may also use arbitrary expressions in `track by`, including references to custom functions
+ * on the scope:
+ * ```html
+ *    <div ng-repeat="n in [42, 42, 43, 43] track by myTrackingFunction(n)">
+ *      {{n}}
+ *    </div>
+ * ```
+ *
+ * <div class="alert alert-success">
+ * If you are working with objects that have an identifier property, you should track
+ * by the identifier instead of the whole object. Should you reload your data later, `ngRepeat`
+ * will not have to rebuild the DOM elements for items it has already rendered, even if the
+ * JavaScript objects in the collection have been substituted for new ones. For large collections,
+ * this significantly improves rendering performance. If you don't have a unique identifier,
+ * `track by $index` can also provide a performance boost.
+ * </div>
+ * ```html
+ *    <div ng-repeat="model in collection track by model.id">
+ *      {{model.name}}
+ *    </div>
+ * ```
+ *
+ * When no `track by` expression is provided, it is equivalent to tracking by the built-in
+ * `$id` function, which tracks items by their identity:
+ * ```html
+ *    <div ng-repeat="obj in collection track by $id(obj)">
+ *      {{obj.prop}}
+ *    </div>
+ * ```
+ *
+ * <div class="alert alert-warning">
+ * **Note:** `track by` must always be the last expression:
+ * </div>
+ * ```
+ * <div ng-repeat="model in collection | orderBy: 'id' as filtered_result track by model.id">
+ *     {{model.name}}
+ * </div>
+ * ```
+ *
+ * # Special repeat start and end points
+ * To repeat a series of elements instead of just one parent element, ngRepeat (as well as other ng directives) supports extending
+ * the range of the repeater by defining explicit start and end points by using **ng-repeat-start** and **ng-repeat-end** respectively.
+ * The **ng-repeat-start** directive works the same as **ng-repeat**, but will repeat all the HTML code (including the tag it's defined on)
+ * up to and including the ending HTML tag where **ng-repeat-end** is placed.
+ *
+ * The example below makes use of this feature:
+ * ```html
+ *   <header ng-repeat-start="item in items">
+ *     Header {{ item }}
+ *   </header>
+ *   <div class="body">
+ *     Body {{ item }}
+ *   </div>
+ *   <footer ng-repeat-end>
+ *     Footer {{ item }}
+ *   </footer>
+ * ```
+ *
+ * And with an input of {@type ['A','B']} for the items variable in the example above, the output will evaluate to:
+ * ```html
+ *   <header>
+ *     Header A
+ *   </header>
+ *   <div class="body">
+ *     Body A
+ *   </div>
+ *   <footer>
+ *     Footer A
+ *   </footer>
+ *   <header>
+ *     Header B
+ *   </header>
+ *   <div class="body">
+ *     Body B
+ *   </div>
+ *   <footer>
+ *     Footer B
+ *   </footer>
+ * ```
+ *
+ * The custom start and end points for ngRepeat also support all other HTML directive syntax flavors provided in AngularJS (such
+ * as **data-ng-repeat-start**, **x-ng-repeat-start** and **ng:repeat-start**).
+ *
+ * @animations
+ * | Animation                        | Occurs                              |
+ * |----------------------------------|-------------------------------------|
+ * | {@link ng.$animate#enter enter} | when a new item is added to the list or when an item is revealed after a filter |
+ * | {@link ng.$animate#leave leave} | when an item is removed from the list or when an item is filtered out |
+ * | {@link ng.$animate#move move } | when an adjacent item is filtered out causing a reorder or when the item contents are reordered |
+ *
+ * See the example below for defining CSS animations with ngRepeat.
+ *
+ * @element ANY
+ * @scope
+ * @priority 1000
+ * @param {repeat_expression} ngRepeat The expression indicating how to enumerate a collection. These
+ *   formats are currently supported:
+ *
+ *   * `variable in expression` – where variable is the user defined loop variable and `expression`
+ *     is a scope expression giving the collection to enumerate.
+ *
+ *     For example: `album in artist.albums`.
+ *
+ *   * `(key, value) in expression` – where `key` and `value` can be any user defined identifiers,
+ *     and `expression` is the scope expression giving the collection to enumerate.
+ *
+ *     For example: `(name, age) in {'adam':10, 'amalie':12}`.
+ *
+ *   * `variable in expression track by tracking_expression` – You can also provide an optional tracking expression
+ *     which can be used to associate the objects in the collection with the DOM elements. If no tracking expression
+ *     is specified, ng-repeat associates elements by identity. It is an error to have
+ *     more than one tracking expression value resolve to the same key. (This would mean that two distinct objects are
+ *     mapped to the same DOM element, which is not possible.)
+ *
+ *     Note that the tracking expression must come last, after any filters, and the alias expression.
+ *
+ *     For example: `item in items` is equivalent to `item in items track by $id(item)`. This implies that the DOM elements
+ *     will be associated by item identity in the array.
+ *
+ *     For example: `item in items track by $id(item)`. A built in `$id()` function can be used to assign a unique
+ *     `$$hashKey` property to each item in the array. This property is then used as a key to associated DOM elements
+ *     with the corresponding item in the array by identity. Moving the same object in array would move the DOM
+ *     element in the same way in the DOM.
+ *
+ *     For example: `item in items track by item.id` is a typical pattern when the items come from the database. In this
+ *     case the object identity does not matter. Two objects are considered equivalent as long as their `id`
+ *     property is same.
+ *
+ *     For example: `item in items | filter:searchText track by item.id` is a pattern that might be used to apply a filter
+ *     to items in conjunction with a tracking expression.
+ *
+ *   * `variable in expression as alias_expression` – You can also provide an optional alias expression which will then store the
+ *     intermediate results of the repeater after the filters have been applied. Typically this is used to render a special message
+ *     when a filter is active on the repeater, but the filtered result set is empty.
+ *
+ *     For example: `item in items | filter:x as results` will store the fragment of the repeated items as `results`, but only after
+ *     the items have been processed through the filter.
+ *
+ *     Please note that `as [variable name] is not an operator but rather a part of ngRepeat micro-syntax so it can be used only at the end
+ *     (and not as operator, inside an expression).
+ *
+ *     For example: `item in items | filter : x | orderBy : order | limitTo : limit as results` .
+ *
+ * @example
+ * This example uses `ngRepeat` to display a list of people. A filter is used to restrict the displayed
+ * results by name. New (entering) and removed (leaving) items are animated.

+/**
+ * @ngdoc directive
+ * @name ngShow
+ * @multiElement
+ *
+ * @description
+ * The `ngShow` directive shows or hides the given HTML element based on the expression
+ * provided to the `ngShow` attribute. The element is shown or hidden by removing or adding
+ * the `.ng-hide` CSS class onto the element. The `.ng-hide` CSS class is predefined
+ * in AngularJS and sets the display style to none (using an !important flag).
+ * For CSP mode please add `angular-csp.css` to your html file (see {@link ng.directive:ngCsp ngCsp}).
+ *
+ * ```html
+ * <!-- when $scope.myValue is truthy (element is visible) -->
+ * <div ng-show="myValue"></div>
+ *
+ * <!-- when $scope.myValue is falsy (element is hidden) -->
+ * <div ng-show="myValue" class="ng-hide"></div>
+ * ```
+ *
+ * When the `ngShow` expression evaluates to a falsy value then the `.ng-hide` CSS class is added to the class
+ * attribute on the element causing it to become hidden. When truthy, the `.ng-hide` CSS class is removed
+ * from the element causing the element not to appear hidden.
+ *
+ * ## Why is !important used?
+ *
+ * You may be wondering why !important is used for the `.ng-hide` CSS class. This is because the `.ng-hide` selector
+ * can be easily overridden by heavier selectors. For example, something as simple
+ * as changing the display style on a HTML list item would make hidden elements appear visible.
+ * This also becomes a bigger issue when dealing with CSS frameworks.
+ *
+ * By using !important, the show and hide behavior will work as expected despite any clash between CSS selector
+ * specificity (when !important isn't used with any conflicting styles). If a developer chooses to override the
+ * styling to change how to hide an element then it is just a matter of using !important in their own CSS code.
+ *
+ * ### Overriding `.ng-hide`
+ *
+ * By default, the `.ng-hide` class will style the element with `display: none!important`. If you wish to change
+ * the hide behavior with ngShow/ngHide then this can be achieved by restating the styles for the `.ng-hide`
+ * class CSS. Note that the selector that needs to be used is actually `.ng-hide:not(.ng-hide-animate)` to cope
+ * with extra animation classes that can be added.
+ *
+ * ```css
+ * .ng-hide:not(.ng-hide-animate) {
+ *   /&#42; this is just another form of hiding an element &#42;/
+ *   display: block!important;
+ *   position: absolute;
+ *   top: -9999px;
+ *   left: -9999px;
+ * }
+ * ```
+ *
+ * By default you don't need to override in CSS anything and the animations will work around the display style.
+ *
+ * ## A note about animations with `ngShow`
+ *
+ * Animations in ngShow/ngHide work with the show and hide events that are triggered when the directive expression
+ * is true and false. This system works like the animation system present with ngClass except that
+ * you must also include the !important flag to override the display property
+ * so that you can perform an animation when the element is hidden during the time of the animation.
+ *
+ * ```css
+ * //
+ * //a working example can be found at the bottom of this page
+ * //
+ * .my-element.ng-hide-add, .my-element.ng-hide-remove {
+ *   /&#42; this is required as of 1.3x to properly
+ *      apply all styling in a show/hide animation &#42;/
+ *   transition: 0s linear all;
+ * }
+ *
+ * .my-element.ng-hide-add-active,
+ * .my-element.ng-hide-remove-active {
+ *   /&#42; the transition is defined in the active class &#42;/
+ *   transition: 1s linear all;
+ * }
+ *
+ * .my-element.ng-hide-add { ... }
+ * .my-element.ng-hide-add.ng-hide-add-active { ... }
+ * .my-element.ng-hide-remove { ... }
+ * .my-element.ng-hide-remove.ng-hide-remove-active { ... }
+ * ```
+ *
+ * Keep in mind that, as of AngularJS version 1.3, there is no need to change the display
+ * property to block during animation states--ngAnimate will handle the style toggling automatically for you.
+ *
+ * @animations
+ * | Animation                        | Occurs                              |

+ * (where you place the directive), place an expression on the **`on="..."` attribute**
+ * (or the **`ng-switch="..."` attribute**), define any inner elements inside of the directive and place
+ * a when attribute per element. The when attribute is used to inform ngSwitch which element to display when the on
+ * expression is evaluated. If a matching expression is not found via a when attribute then an element with the default
+ * attribute is displayed.
+ *
+ * <div class="alert alert-info">
+ * Be aware that the attribute values to match against cannot be expressions. They are interpreted
+ * as literal string values to match against.
+ * For example, **`ng-switch-when="someVal"`** will match against the string `"someVal"` not against the
+ * value of the expression `$scope.someVal`.

+ * @ngdoc directive
+ * @name ngTransclude
+ * @restrict EAC
+ *
+ * @description
+ * Directive that marks the insertion point for the transcluded DOM of the nearest parent directive that uses transclusion.
+ *
+ * You can specify that you want to insert a named transclusion slot, instead of the default slot, by providing the slot name
+ * as the value of the `ng-transclude` or `ng-transclude-slot` attribute.
+ *
+ * If the transcluded content is not empty (i.e. contains one or more DOM nodes, including whitespace text nodes), any existing
+ * content of this element will be removed before the transcluded content is inserted.
+ * If the transcluded content is empty, the existing content is left intact. This lets you provide fallback content in the case
+ * that no transcluded content is provided.
+ *
+ * @element ANY
+ *
+ * @param {string} ngTransclude|ngTranscludeSlot the name of the slot to insert at this point. If this is not provided, is empty
+ *                                               or its value is the same as the name of the attribute then the default slot is used.
+ *
+ * @example
+ * ### Basic transclusion

+ * @ngdoc directive
+ * @name select
+ * @restrict E
+ *
+ * @description
+ * HTML `SELECT` element with angular data-binding.
+ *
+ * The `select` directive is used together with {@link ngModel `ngModel`} to provide data-binding
+ * between the scope and the `<select>` control (including setting default values).
+ * It also handles dynamic `<option>` elements, which can be added using the {@link ngRepeat `ngRepeat}` or
+ * {@link ngOptions `ngOptions`} directives.
+ *
+ * When an item in the `<select>` menu is selected, the value of the selected option will be bound
+ * to the model identified by the `ngModel` directive. With static or repeated options, this is
+ * the content of the `value` attribute or the textContent of the `<option>`, if the value attribute is missing.
+ * If you want dynamic value attributes, you can use interpolation inside the value attribute.
+ *
+ * <div class="alert alert-warning">
+ * Note that the value of a `select` directive used without `ngOptions` is always a string.
+ * When the model needs to be bound to a non-string value, you must either explicitly convert it
+ * using a directive (see example below) or use `ngOptions` to specify the set of options.
+ * This is because an option element can only be bound to string values at present.
+ * </div>
+ *
+ * If the viewValue of `ngModel` does not match any of the options, then the control
+ * will automatically add an "unknown" option, which it then removes when the mismatch is resolved.
+ *
+ * Optionally, a single hard-coded `<option>` element, with the value set to an empty string, can
+ * be nested into the `<select>` element. This element will then represent the `null` or "not selected"
+ * option. See example below for demonstration.
+ *
+ * <div class="alert alert-info">
+ * In many cases, `ngRepeat` can be used on `<option>` elements instead of {@link ng.directive:ngOptions
+ * ngOptions} to achieve a similar result. However, `ngOptions` provides some benefits, such as
+ * more flexibility in how the `<select>`'s model is assigned via the `select` **`as`** part of the
+ * comprehension expression, and additionally in reducing memory and increasing speed by not creating
+ * a new scope for each repeated instance.
+ * </div>
+ *
+ *
+ * @param {string} ngModel Assignable angular expression to data-bind to.
+ * @param {string=} name Property name of the form under which the control is published.
+ * @param {string=} multiple Allows multiple options to be selected. The selected values will be
+ *     bound to the model as an array.
+ * @param {string=} required Sets `required` validation error key if the value is not entered.
+ * @param {string=} ngRequired Adds required attribute and required validation constraint to
+ * the element when the ngRequired expression evaluates to true. Use ngRequired instead of required
+ * when you want to data-bind to the required attribute.
+ * @param {string=} ngChange Angular expression to be executed when selected option(s) changes due to user
+ *    interaction with the select element.
+ * @param {string=} ngOptions sets the options that the select is populated with and defines what is
+ * set on the model on selection. See {@link ngOptions `ngOptions`}.

+ *
+ * The directive sets the `required` attribute on the element if the Angular expression inside

+ * for more info.
+ *
+ * The validator will set the `required` error key to true if the `required` attribute is set and
+ * calling {@link ngModel.NgModelController#$isEmpty `NgModelController.$isEmpty`} with the
+ * {@link ngModel.NgModelController#$viewValue `ngModel.$viewValue`} returns `true`. For example, the
+ * `$isEmpty()` implementation for `input[text]` checks the length of the `$viewValue`. When developing
+ * custom controls, `$isEmpty()` can be overwritten to account for a $viewValue that is not string-based.

+   * and functions can be chained together. Methods that retrieve a single value
+   * or may return a primitive value will automatically end the chain sequence
+   * and return the unwrapped value. Otherwise, the value must be unwrapped
+   * with `_#value`.
+   *
+   * Explicit chain sequences, which must be unwrapped with `_#value`, may be
+   * enabled using `_.chain`.
+   *
+   * The execution of chained methods is lazy, that is, it's deferred until
+   * `_#value` is implicitly or explicitly called.
+   *
+   * Lazy evaluation allows several methods to support shortcut fusion.
+   * Shortcut fusion is an optimization to merge iteratee calls; this avoids
+   * the creation of intermediate arrays and can greatly reduce the number of
+   * iteratee executions. Sections of a chain sequence qualify for shortcut
+   * fusion if the section is applied to an array and iteratees accept only
+   * one argument. The heuristic for whether a section qualifies for shortcut
+   * fusion is subject to change.
+   *
+   * Chaining is supported in custom builds as long as the `_#value` method is
+   * directly or indirectly included in the build.
+   *
+   * In addition to lodash methods, wrappers have `Array` and `String` methods.
+   *
+   * The wrapper `Array` methods are:
+   * `concat`, `join`, `pop`, `push`, `shift`, `sort`, `splice`, and `unshift`
+   *
+   * The wrapper `String` methods are:
+   * `replace` and `split`
+   *
+   * The wrapper methods that support shortcut fusion are:
+   * `at`, `compact`, `drop`, `dropRight`, `dropWhile`, `filter`, `find`,
+   * `findLast`, `head`, `initial`, `last`, `map`, `reject`, `reverse`, `slice`,
+   * `tail`, `take`, `takeRight`, `takeRightWhile`, `takeWhile`, and `toArray`
+   *
+   * The chainable wrapper methods are:
+   * `after`, `ary`, `assign`, `assignIn`, `assignInWith`, `assignWith`, `at`,
+   * `before`, `bind`, `bindAll`, `bindKey`, `castArray`, `chain`, `chunk`,
