---------------------------------------------------------------------- 

Modified Files:
 	Namespaces.py -- added a bunch of namespaces (encryption, ws-address, ws-resourcepolicy, etc)

        WSDLTools.py -- added functionality for getting WS-ResourceProperties and
           ws-Address information out of WSDL.  Ran all unittests and passed.
