[x3d-public] x3d.py works in web browser with brython. No Jupyter needed AFAIK!

[John Carlson]

We should now be able to get python x3d.py X3DPSAIL working on web again.

The solution is brython, a python package, implementation of python in JS.

Uses, X3DOM, may try for an X_ITE version.

Hint:  Use a local version of brython, not CDN.

If someone wants to see the results, I can zoom.
