VERSION: 1.0

ACTIONSCRIPT VERSION: 3.0
DESCRIPTION:
	This class works in conjunction with the TweenLiteVars or TweenMaxVars class to grant
	strict data typing and code hinting (in most code editors) for transformAroundPoint tweens. See the documentation in
	the TweenLiteVars or TweenMaxVars for more information.

USAGE:
	
	Instead of TweenMax.to(my_mc, 1, {transformAroundCenter:{scaleX:2, scaleY:1.5, rotation:30}}, onComplete:myFunction}), you could use this utility like:
	
		var myVars:TweenMaxVars = new TweenMaxVars();
		myVars.transformAroundPoint = new TransformAroundCenterVars(2, 1.5, 30);
		myVars.onComplete = myFunction;
		TweenMax.to(my_mc, 1, myVars);
		
		
NOTES:
	- This utility is completely optional. If you prefer the shorter synatax in the regular TweenLite/TweenMax class, feel
	  free to use it. The purpose of this utility is simply to enable code hinting and to allow for strict data typing.
	- You cannot define relative tween values with this utility.
