Modified files:
        gnue-common/gnue/common: GDebug.py 

Log message:
        Completed GDebug.py so that it handles traces, exceptions, and writing 
to log files. Will be used transparently by new GClientApp class. Note that 
this file is not exactly the same as GFDebug, although this file supercedes 
GFDebug.  The printMesg works the same. However, to set the log file and 
debugging level, run GDebug.setDebug(level, file).  If file==None then stderr 
is used.
