[x3d-public] removeNamedNode removes DEF children?

[Andreas Plesch]

This applies to how removing a DOM node with x3dom should behave. From an
X3D point of view it probably should behave like group.removeChildren,
which x3dom does. That means removing a DOM DEF node does not have an
effect on a USE node.

But from a DOM programming perspective this may be surprising since the USE
instance now seems to refer to a null value.

I think improving documentation may be all what is needed.

Thanks again, Andreas
