+/**
+ * @class NamesValues
+ *
+ * Builds up a string of name=value pairs for use in
+ * situations like error log metadata.
+ *
+ * Names and values can be added to an instance of this
+ * class, and then calling get() will return a string
+ * that appends them all together.
+ *
+ * Currently, just uint64_t values that will be displayed
+ * in hex are supported.
+ *
+ * For example:
+ *     NamesValues m;
+ *     uint8_t d = 0xFF;
+ *
+ *     m.add("STATUS_VOUT", d);
+ *     m.add("STATUS_WORD", 0xABCD);
+ *
+ *     m.get() //returns: "STATUS_VOUT=0xFF|STATUS_WORD=0xABCD"
