[x3d-public] Discussion: containerField for x3d.py XML export

[John Carlson]

If it wasn’t clear, i was going to add a “containerField” optional
parameter to some XML() methods in x3d.py

I put in containerField into where view3dscene complains and the problem
goes away, I know exactly what the problem is.  I will provide a file
later, sorry for the delay.

The goal is to do no editing except for meta statements.
