[x3d-public] node-java X3DJSAIL and 1 example that works, and one that doesn't

[John Carlson]

Could Andreas explain how to use createNode in the context of X_ITE SAI?
I think that createNode may be the one significant thing missing from X3DOM
SAI.
There's an unrelated one in the physics code.

That is, you use createNode to createNodes in SAI, then you use the fields
of the returned object.  Are these the same across browsers?

Here's how to get a node from the standard:

Browser.currentScene.createNode('Shape');

Again, there is no createNode in X3DJSAIL to speak of.

Thanks,

John
