[GEM-dev] more new primitive for gem...

[guenter geiger]

I have not yet been able to try the new externals, but I'd like to
share a thought about geometric objects that I had, and that
is the implementation of NURBS objects. I think this could
make manipulations possible that have been hard to implement up to now in
GEM.
