Log message:
	Classes Constraint and Generator now have comparison operators == and !=,
	checking for semantic equivalence.
	Class constraint has publicly available methods is_tautological() and
	is_inconsistent(), replacing the preovate methods is_trivial_true() and
	is_trivial_false().
	The swap methods of classes Constraint, Generator, Linear_Expression,
	Constraint_System and Generator_System are now publicly available.
	Corrected a minor efficiency bug in Polyhedron::shrink_bounding_box().
