Correct for the top-level USE node references.  However use addChild for constructing the skeleton.

Please see Javadoc and examples.

> What is the correct method for adding a joint to a humanoid?  Source not attached because of size.    There may not be a way to do this in X3D 3.3.  I am not sure.  I will get around to checking the object model eventually, but if anyone knows without looking.  It probably has something to do with the field the joint goes in, like skin, etc.
