Modified files:
	src            : Polyhedron.cc 

Log message:
	In functions Polyhedron::update_constraints and Polyhedron::update_generators
	we only have a saturation matrix up-to-date: so, we must say that the other
	is not up-to-date.
	In function Polyhedron::assign_variable, if the transformation is not
	invertible, we must have the system of generators up-to-date, and then
	if the polyhedron is non-empty, we use the function GenSys::assign_variable
	to find the resulting polyhedron. so, we always modify the polyhedron (we do
	not modify the polyhedron if it is empty or if there are dimensional
	problems).
