[x3d-public] X3DGroupingNode interface has no method setIS in X3DJSAIL, FYI

[John Carlson]

Thank you all for considering this code.  Note that one works, and here is the failure for the other. It appears when you use concrete classes and not interfaces, it works.  The interface does not have the method.   We will have to figure out some kind of casting scheme, I think.
