/** \class plAGMasterMod
	A modifier which can apply animations to scene objects. 
	Works together with a plAGModifier, which can apply animation to a
	single scene object. A master modifier hooks up to a family of
	ag modifiers to do its job.
	An animation (plAGAnim) can have many different channels, but the
	user can just pass it to a single master mod to apply it to all the
	channels owned by that master. The master will take care of hooking
	each channel up to an ag modifier.
	The goal is to make an animation a conceptually (and practically) simple
	object to work with, whether or not it has multiple channels.
