Classes
 ClassDescription
 CirclePath2D A CirclePath2D defines a circular path on which a PathFollower can be placed, making it simple to tween objects along a circle or oval (make an oval by altering the width/height/scaleX/scaleY properties).
 Direction Constants for defining the direction in which to travel on a MotionPath (like CLOCKWISE, COUNTER_CLOCKWISE, SHORTEST, etc.).
 LinePath2D A LinePath2D defines a path (using as many Points as you want) on which a PathFollower can be placed and animated.
 MotionPath A MotionPath defines a path along which a PathFollower can travel, making it relatively simple to do things like tween an object in a circular path.
 PathFollower A PathFollower is used to associate a particular target object (like a MovieClip, Point, Sprite, etc.) with a MotionPath and it offers a tweenable progress property that manages positioning the target on the path accordingly.
 RectanglePath2D A RectanglePath2D defines a rectangular path on which a PathFollower can be placed, making it simple to tween objects along a rectangle's perimeter.
