OverwriteManager OverwriteManager resolves conflicts between tweens and controls if (and how) existing tweens of the same target are overwritten.
 TimelineLite TimelineLite is a lightweight, intuitive timeline class for building and managing sequences of TweenLite, TweenMax, TimelineLite, and/or TimelineMax instances.
 TimelineMax TimelineMax extends TimelineLite, offering exactly the same functionality plus useful (but non-essential) features like AS3 event dispatching, repeat, repeatDelay, yoyo, currentLabel, addCallback(), removeCallback(), tweenTo(), tweenFromTo(), getLabelAfter(), getLabelBefore(), and getActive() (and probably more in the future).
 TweenAlign Static constants for defining tween alignment.
 TweenLite TweenLite is an extremely fast, lightweight, and flexible tweening engine that serves as the foundation of the GreenSock Tweening Platform.
 TweenMax TweenMax extends the extremely lightweight, fast TweenLite engine, adding many useful features like timeScale, event dispatching, updateTo(), yoyo, repeat, repeatDelay, rounding, and more.
 TweenNano TweenNano is a super-lightweight (1.6k in AS3 and 2k in AS2) version of TweenLite and is only recommended for situations where you absolutely cannot afford the extra 3.1k (4.7k total) that the normal TweenLite engine would cost and your project doesn't require any plugins.
 TweenProxy TweenProxy essentially "stands in" for a DisplayObject, adding several tweenable properties as well as the ability to set a custom registration point around which all transformations (like rotation, scale, and skew) occur.
