[x3d-public] another new X3DJSAIL feature: isNode() and isStatement() methods

[Don Brutzman]

Have added boolean utility methods X3DConcreteNode.isNode(), 
X3DConcreteStatement.isStatement() and CommentsBlock.isStatement() etc.

Thus you have the ability to ask any node or any statement whether it is a node 
or statement.  These are static methods, so you can apply them to instances or 
to classes.  Such tests might be helpful when you are creating schema-like files 
programmatically.

As before, the validate() method for each node and statement has as many checks 
as I can devise in there.  Pretty much everything from object model.  Haven't 
cross-checked with X3D Schematron yet... identification of further gaps is 
always welcome.

all the best, Don
