 * VERSION: 0.10.0
 * DATE: 2014-02-20
 * UPDATES AND DOCS AT: http://www.greensock.com
 *
 * Requires TweenLite and CSSPlugin version 1.11.0 or later (TweenMax contains both TweenLite and CSSPlugin). ThrowPropsPlugin is required for momentum-based continuation of movement after the mouse/touch is released (ThrowPropsPlugin is a membership benefit of Club GreenSock - http://www.greensock.com/club/).
