Modified files:
	src            : BD_Shape.defs.hh BD_Shape.inlines.hh 

Log message:
	Added a new function extract_bounded_difference() to factorize repeated
	code for decoding a constraint.
	A lot of repeated code also factorized in method relation_with().
	Added a private method BD_Shape<T>::get_limiting_constraints() to be
	used in the implementations of limited widening operators.
	Prefer assign() to the direct assignment operator when assigning zero.
	Removed a couple of improper usages of the Coefficient_traits template.
