c50156360a Fixed bug in searchPath function for finding nodes between two recurrences. 
Changed dependence analyzer to only use dep distances of 2 or less.
This is experimental.

Changed MSchedGraph to be able to represent more then one BB (first steps).

eba4604d49 Make this method non-const. Making it const causes the const version of 
getIGroup to be called instead of the non-const one.  These two methods
have (??) different behavior, so this change fixes bugs.
