This has been fixed in my local repository. I have to clean up it a bit, but ATM I have only rarely internet access
since I am on vacation. Will send a patch next week.

> If a tetrahedron and triangle (converted from MeshEntities to CGAL Nef_polyhedron_3) are intersected and resulting polygon has non-vanishing area, BarycenterQuadrature computes quadrature wrong. Actually it gives zero area, since some loops are not entered in the BarycenterQuadrature::compute_quadrature function. (Such a intersection object has surprisingly *NO* half_facets). Check against CGAL is needed.
