Hi,

	I'm having an awful lot of trouble successfully building Nef  
Polyhedra from .off input files.  The only model I have successfully  
translated from .off to a Nef Polyhedron and back is a cube.  I have  
tried a number of different models, all supposed to be watertight,  
and which were certified by the Polyhedron_3::is_closed() function.   
It certainly may be the case that there was something off (ba dum  
chh) about these models, but I've reached my point of frustration.   
If anyone has any known working examples of importing models into the  
Nef Polyhedron type, or any suggestions, I would much appreciate the  
tips.
