 * Provides a basic `Backbone.Router` to route between app states: `all`, `active` & `completed`. When a user
 * navigates between these different filter type states `Backbone.history.navigate` is invoked in `App->selectFilter`
 * to update the navigation history allowing the user to use the back and forward browser controls to navigate the app.
 * When a filter type is selected it is referenced in the current URL for the web app. 
 *
 * Please note that in `App.js->s_INITIALIZE_ROUTES` a default catch all no route callback is specified which handles
 * unmatched routes.
