   Purpose: This file contains the class for a map between the BasicBlock class
            and the BBLiveVar class, which is a wrapper class of BasicBlock
	    used for the live variable analysis. The reverse mapping can
	    be found in the BBLiveVar class (It has a pointer to the 
	    corresponding BasicBlock)
