* <img src="Images/AnimationWidget.png" width="211" height="142" alt="" />
* <br />Animation widget
* </span>
* <br /><br />
* The Animation widget provides buttons for play, pause, and reverse, along with the
* current time and date, surrounded by a "shuttle ring" for controlling the speed of animation.
* <br /><br />
* The "shuttle ring" concept is borrowed from video editing, where typically a
* "jog wheel" can be rotated to move past individual animation frames very slowly, and
* a surrounding shuttle ring can be twisted to control direction and speed of fast playback.
* Cesium typically treats time as continuous (not broken into pre-defined animation frames),
* so this widget offers no jog wheel. Instead, the shuttle ring is capable of both fast and
* very slow playback. Click and drag the shuttle ring pointer itself (shown above in green),
* or click in the rest of the ring area to nudge the pointer to the next preset speed in that direction.
* <br /><br />
* The Animation widget also provides a "realtime" button (in the upper-left) that keeps
* animation time in sync with the end user's system clock, typically displaying
* "today" or "right now." This mode is not available in {@link ClockRange.CLAMPED} or
* {@link ClockRange.LOOP_STOP} mode if the current time is outside of {@link Clock}'s startTime and endTime.
*
* @alias Animation
* @constructor
*
* @param {Element|String} container The DOM element or ID that will contain the widget.
* @param {AnimationViewModel} viewModel The view model used by this widget.
*
* @exception {DeveloperError} Element with id "container" does not exist in the document.
