[x3d-public] Python, the emperor has no clothes!

[John Carlson]

testing toXML in python.   BackgroundCollection.py works.

These don't:
$ python HelloWorld.py
x3d.py package loaded, have fun with X3D Graphics!
Traceback (most recent call last):
  File "HelloWorld.py", line 77, in <module>
    print (     newModel.toXML())

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

Appearance is an SFNode, so it's not a iterable.
