[XML-SIG] 4DOM checked into PyXML CVS

[Andrew Kuchling]

I've just checked in a snapshot of 4DOM into the XML-SIG's CVS tree.
This will probably result in massive breakage of code that uses the
DOM, or one of the modules in xml.dom that got deleted.  Current goals
are to test more of the new DOM code, and fix any breakages.  I've
already spotted a few minor glitches, and will send the patches back
to FourThought.
