[x3d-public] x3d.py error; fixed and deployed

[Don Brutzman]

Thanks for trouble report.  This was similar to error a few days ago, common cause was incorrect handling of MFString fields by toXML() method.

Now fixed and deployed.  I've performed regression tests on about 4000 models, have ~30 Traceback errors to continue diagnosis on.  So... toXML() is pretty much implemented now!

* Python X3D Package x3d.py
   X3D Python Scene Access Interface Library (X3DPSAIL)
   https://www.web3d.org/x3d/stylesheets/python/python.html

* pip install x3d; Python package x3d
   https://pypi.org/project/x3d

Further improvement suggestions and bug reports welcome.  Hoping to complement other work, today's Design Printing Scanning demo was great - thanks very much.

Have fun with X3D Python!
