/**
 * This is a node that contains a pointer to an PartBundle.  Like
 * AnimBundleNode, it exists to make it easy to store PartBundles in the scene
 * graph.
 *
 * (Unlike AnimBundleNode, however, PartBundleNode has an additional function:
 * it is also the base class of the Character node type, which adds additional
 * functionality.)
