[x3d-public] Upcoming feature of X3DJSAIL. A Java based X3DJSONLD!

[Don Brutzman]

John, this emerging X3D interoperability between java/javascript/.x3d/.json seems really significant.  Can we make sure that it is properly & consistently documented in X3DJSAIL to correspond with X3DJSONLD?

Alternately a few more TODO items will emerge...  probably crafting and exposing a few examples that deliberately try to "ring all the bells at once" will be a useful exercise to share.

Thanks for your efforts.
