/** \class plAGModifier
Animates a single scene object.
May apply multiple animations to that scene object, animating
the transform with one, colors with another, etc.
The basic model is that the ag modifier holds an array of
applicators, each of which is the root of a tree of animation
operations, such as a blend tree, etc. Each frame it fires
all its applicators, or (ideally) only those that need to be fired.
