Modified files:
	src            : Polyhedra_PowerSet.inlines.hh 

Log message:
	Corrected a bug in pairwise_reduce(), whereby we were marking the wrong
	polyhedra in the sequence.
	Corrected a bug in BHZ03_widening_assign(), whereby we were calling
	BGP99_extrapolation_assign() instead of BGP99_heuristics_assign
	(the latter does not pairwise-reduce nor collapse the sequence of polyhedra).
	In the implementation of BGP99_heuristics_assign(), we now take a copy of
	polyhedron `pi' before computing the base-level widening.
