+ * The Ease class provides a collection of easing functions for use with TweenJS.
+ * It does not use the standard 4 param easing signature. Instead it uses a single param
+ * which indicates the current linear ratio (0 to 1) of the tween.<br/>
+ * <br/>
+ * Most methods on Ease can be passed directly as easing functions:<br/>
+ * Tween.get(target).to({x:100}, 500, Ease.linear);<br/>
+ * <br/>
+ * However, methods beginning with "get" will return an easing function based on parameter values:<br/>
+ * Tween.get(target).to({y:200}, 500, Ease.getPowIn(2.2));<br/>
+ * <br/>
+ * Equations derived from work by Robert Penner.
