Modified files:
	src            : Polyhedron.defs.hh Polyhedron.cc 

Log message:
	Added new private method
	void Polyhedron::select_H79_constraints(const Polyhedron& y,
	ConSys& cs_selection) const;
	that selects the common constraints of *this and y (into cs_selection)
	according to H79.
	Used the method both in H79_widening and in BBRZ02_widening.
	Modified the second technique of BBRZ02 to have more chances that it
	will produce a stabilizing sequence of polyhedra.
	Added a few outputs for the debugging of BBRZ02_widening.
