/****h* OpenSM/Multicast Tree
* NAME
*	Multicast Tree
*
* DESCRIPTION
*	The Multicast Tree object encapsulates the information needed by the
*	OpenSM to manage multicast fabric routes.  It is a tree structure
*	in which each node in the tree represents a switch, and may have a
*	varying number of children.
*
*	Multicast trees do not contain loops.
*
*	The Multicast Tree is not thread safe, thus callers must provide
*	serialization.
*
*	This object should be treated as opaque and should be
*	manipulated only through the provided functions.
