 - Add models to wrap yuidoc json
 - Add helper methods for querying relationships from the store
   similar in spirit to DS.hasMany and DS.belongsTo

Components

- Pass models to the components instead of the entire store
- Make naming more consistent

Routes, Templates & Friends

- Minor tweaks to fit the DOM to the CSS
- Hook up inherited/private/protected/deprecated tabs
- Add more routes so methods/properties/events are linkable

Miscellaneous

- Remove ember-data dependency
