Modified Files:
        ** removed all "imports" of ZSI or ZSI.wstools, so wstools
        can be used independently by SOAPpy.

 	Namespaces.py
        -- added a namespace

        Utility.py
        -- moved ZSI.utility here, and the "Base" class for logging.

        WSDLTools.py
        -- added a "toDom" and "GetWSDL" methods to several classes,
        so now you can construct a WSDL instance and then call
        WSDL.toDom() --> DOM --> and create a WSDL file.

        __init__.py
        -- removed "Base" class for logging.

 Added Files:
 	c14n.py
        -- moved the c14n stuff from ZSI.compat here.

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

Modified Files:
 	XMLSchema.py
        -- added a few convience methods, and 'disabled' a few methods
        to force a sane usage.

        __init__.py
        -- removed use of python logging module, and replaced it with
        the below.

 Added Files:
 	logging.py
        -- simple interface to log message to, can write your own
        logger class.  By default do no logging.

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

Modified Files:
 	__init__.py -- changed "Base", which contains a logger, to
           no-op logging if the logging configuration file is not
           found and avoid the overhead of using the logging module.

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

commit a little while ago. :)  That is, wstools is now independant
of SOAPpy and ZSI.  This commit does the following:
    wstools/ServiceProxy.py is now ZSI/ServiceProxy.py, so some
    imports and ZSI docs had to change.
ZSI needs some changing, in case I didn't patch up all the imports
right.
