	//   A pager can be defined one of two ways:
	//    * Externally of the RotatorContainer's template and tell the
	//      RotatorPager the rotatorId of the RotatorContainer
	//    * As a direct descendant of the RotatorContainer (i.e. inside the
	//      RotatorContainer's template)
	//
	//   The pager can contain the following components:
	//    * Previous button
	//      - Must be a dijit.form.Button
	//      - dojoAttachPoint must be named "previous"
	//    * Next button
	//      - Must be a dijit.form.Button
	//      - dojoAttachPoint must be named "next"
	//    * Play/Pause toggle button
	//      - Must be a dijit.form.ToggleButton
	//      - dojoAttachPoint must be named "playPause"
	//      - Use iconClass to specify toggled state
	//    * Current child #
	//      - dojoAttachPoint must be named "current"
	//    * Total # of children
	//      - dojoAttachPoint must be named "total"
	//
	//   You can choose to exclude specific controls as well as add elements
	//   for styling.
	//
	//   Should you need a pager, but don't want to use Dijit buttons, you can
	//   write your own pager widget and just wire it into the topics.  The
	//   topic names are prefixed with the widget ID of the RotatorContainer.
	//   Notifications are received from and sent to the RotatorContainer as
	//   well as other RotatorPagers.
	//
	// published topics:
	//   [widgetId]-cycle - Notify that the next or previous button was pressed.
	//      Parameters:
	//        /*boolean*/ next - true if next, false if previous
	//   [widgetId]-state - Notify that the play/pause button was toggled.
	//      Parameters:
	//        /*boolean*/ playing - true if playing, false if paused
	//
	// example:
	//   A pager with the current/total children and previous/next buttons.
