The builds will fail to due valid flake8 problems. Anyome is welcomed to solve some of them as I will not make a new release before they are all fixed.

-- go thru the parent/etc attributes first, then the current nodes,
	then the current node's namespace nodes will override parent ones.

-- fix for exclusive c14n, fairly extensive changes were necessary to
	pass down dict of unused prefix:namespace mappings.
	
        <... xmlns:ns1="urn:bla" xmlns:ns2="urn:bla2"..
          <CanonicalizeMe
             <...
		<ns1:whatever>


       So now if I do an exclusive of "CanonicalizeMe" now the xmlns:ns1="urn:bla" 
       will be added to ns1:whatever element

Modified Files:
 	c14n.py -- fixed a bug affecting those who don't have pyXML installed.
 ----------------------------------------------------------------------

Modified Files:
 	c14n.py -- just removed import of ZSI so SOAPy can use
		w/o ZSI.
 ----------------------------------------------------------------------

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.
