// 	 Class : MultiNodeTransition
// Description : This is a particular instantiation of MultiTransition
//               on PT_Node.  It is its own class in an attempt to
//               cut down on code bloat; if a particular transition
//               wants to be a MultiTransition on some kind of
//               Node, it should inherit from MultiNodeTransition
//               (rather than instantiating a whole new kind of
//               MultiTransition).
