+// CLASS DESCRIPTION (MAnimCurveChange)
+//
+//	Anim Curve Change caches are used as persistent storage for information
+//	concerning changes to Anim Curve Nodes.
+//
+//	When invoked with a valid Anim Curve change parameter, the remove keyframe
+//	and	add keyframe methods of the Anim Curve Function Set
+//	(MFnAnimCurve::remove()	and MFnAnimCurve::addKeyframe(), respectively)
+//	cache the change information in the Anim Curve Change cache so that the
+//	caller can undo and redo the changes as required.
+//
+//	Caching of the undo and redo information in a Anim Curve Change cache is
+//	required primarily to support interactive editing of Anim Curves in the UI.
+//
+//	Use Anim Curve Change caches in conjunction with the Anim Curve Function
+//	Set (MFnAnimCurve) to perform undoable and redoable edits on Anim Curves.
