I'm not very familiar with the UNV format either, but it seems that we 
don't print the surface mesh when there is a volume in the CAD whose 
boundary contains this surface. I'm not sure why it's coded up this 
way... JF: any comments?

If nobody objects, I will change this behavior so that we always save 
all the elements.
