  //     the controller (as used in the routes) and the value should be a
  //     controller _constructor_.
  //   * **controllerOptions**, optional options passed to controller
  //     constructor.
  //   * **routeCallback**, passed as the last argument to the route action.

  // monitoring the URL for changes.
