Modified files:
	src            : SatRow.cc SatRow.defs.hh simplify.cc 

Log message:
	New function
	bool subset_or_equal(const SatRow& x, const SatRow& y, bool& strict_subset)
	allows a simple optimization of Polyhedron::simplify().
	The function bool strict_subset(const SatRow& x, const SatRow& y)
	is currently unused but left in place: it may be needed and, moreover,
	when all what matters is strict inclusion, `strict_subset(x, y)' is faster
	than `subset_or_equal(x, y, s) && s'.
