Hi Tim-

I'd like to remove this code from CVS temporarily. We need to clear up the 
copyright, I do not want any GPL'd code in there, it is confusing to 
customers and users. Can we try to resolve the copyright, get permission to 
put the VTK copyright on? I can help with this if necessary. Also I'd like 
to clean up the code before it's officially part of VTK...there's too much 
code there and I'm afraid it will languish like the VRMLImporter did...it 
took several years to get the code warning and leak free.

Will
