Update of /thubanrepository/thuban/Extensions/wms
In directory doto:/tmp/cvs-serv3794

Modified Files:
	layer.py 
Log Message:
Move away from using only one layer to using a list of layers
(unsorted at the moment, though).  Added two convenience methods for
retrieving and setting the list of visible layers (get/setVisibleLayers)
