Update navigation to accordian-style menu

- New navigation provides intuitive structure for showing relationship
between sections and pages
- Menu keeps an open state, which allows easy clicking to sibling pages
- Ability to preview all page sections w/o hover over blocking page content
- Allows user to see where they are within navigation at all times

Tested: Opened each page and confirmed new navigation worked, clicked through
to all pages successfully.
