Log message:
	Added support for the consident use of bidirectional iterators (iterator,
	const_iterator, reverse_iterator, const_reverse_iterator) for the class
	Powerset. The new iterators replace the low-level ones on the sequence
	of disjuncts, which are now protected and were not enforcing the
	consistency of the reduced flag. All the new iterators only provide
	read-only access to the disjuncts in a Powerset element.
	It is possible to drop elements form the sequence (but not to directly
	modify them) by using `iterator' in conjunction with Powerset<CS>
	methods drop_disjunct(), drop_disjuncts() and clear().
