[x3d-public] X3D APIS for Qt, Python, ECMAScript

[John Carlson]

Here is X3DTSSAIL:

https://coderextreme.net/X3DTSSAIL.zip

Does this satisfy the desire for ECMAscript, or do we want a native JSON
scenegraph?   Can we add it to X3DJSAIL?   We should be able to extract
JSON and parse JSON already?   I think?   Do you need examples?

I will spend some time looking at x3d.py generation.
