// COMMENTS:
//
// Input is assumed to be a sequence of lines of the form:
//	I	Global ID of branch root
//	II	Value of supernode
//	III	Global ID of supernode
//
//	All lines are assumed to have been sorted already.  Because of how the
//      Unix sort utility operates (textual sort), the most we can assume is that all
//      supernodes corresponding to a given branch root are sorted together.
//
//	We therefore do simple stream processing, identifying new branches by
//      the changes in root ID.
