   MODEL FACE OPERATORS:

 void GF_Regions(PGeomFace gf, PGeomRegn gr[2]);

Get the regions on either side of the face. gr[0] is the region on the

opposite side of the normal while gr[1] is the region on the same side

of the normal.  In principle (not in LaGriT), both entries of gr may

be filled _AND_ gr[0] may be equal to gr[1]. Also in principle, both

entries of gr may be NULL.
