[Tinyos-commits] CVS: tinyos-1.x/tools/python/pytos Comm.py, 1.1, 1.2

[Kamin Whitehouse]

Update of /cvsroot/tinyos/tinyos-1.x/tools/python/pytos
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv871

Modified Files:
	Comm.py 
Log Message:
Added register/unregister functions to Drip and RamSymbols and updated the messageSnooper to know how to snoop on these messages.  Added "get" functions to comm, drip and drain, so that only a single instance of each needs to be instantiated.  Added a logically "negative" message filter.
