+   Date:    Jun 30, 01
+   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)
