Modified files:
	src            : Octagonal_Shape.templates.hh 

Log message:
	Use is_additive_inverse() to improve readability in several places.
	Used is_even() in tight_coherence_would_make_empty().
	Corrected bug in the output operator whereby the output of an octagon
	having integer coefficients could have been innacurate (but correct).
