-/* Title:   InterferenceGraph.h   -*- C++ -*-
-   Author:  Ruchira Sasanka
-   Date:    July 20, 01
-   Purpose: Interference Graph used for register coloring.
-
-   Notes: 
-   Adj Info is  stored in the lower trangular matrix (i.e., row > col ) 
-
-   This class must be used in the following way:
-
-   * Construct class
-   * call addLRToIG as many times to add ALL LRs to this IG
-   * call createGraph to create the actual matrix
-   * Then setInterference, getInterference, mergeIGNodesOfLRs can be 
-     called as desired to modify the graph.
-   * Once the modifications to the graph are over, call 
-     setCurDegreeOfIGNodes() before pushing IGNodes on to stack for coloring.
