Modified files: src : Polyhedron_public.cc

Log message: Corrected the method for simplification of polyhedra wrt context so that to avoid converting a masked equality (i.e., an inequality that implies an equality in the given context) to a proper equality; for instance, now simplifying PH1 = { A >= 0 } in the context of PH2 = { A <= 0 } returns PH1, instead of PH3 = { A == 0 }. The correction ensures that the method is extensive on the polyhedra domain and hence solves the corresponding bug in the Pointset_Powerset domain.
