Modified files: src : Polyhedron.cc

Log message: Some improvements to the third technique of Polyhedron::BBRZ02_widening_assign(): - the test y.relation_with(x_g) == Poly_Gen_Relation::nothing() is done after testing if x_g is a ray; - corrected the test of the elements of the vector "considered"; - now we use a const reference x_g (for x.gen_sys[i]) to find how it evolved since a ray of "y" and a copy of "x_g" to built the new ray. Use "H79_con_sys" instead of "common_con_sys" in Polyhedron::BBRZ02_widening_assign() and in Polyhedron::H79_widening_assign().
