// summary:
// Defines controls used to manipulate a RotatorContainer
//
// description:
// 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.

// | <button dojoType="dijit.form.Button" dojoAttachPoint="previous">Prev</button>
