Log message:
	Update Grid::normalize_divisors(sys,d,f) to simply return zero when
	the given divisor is zero.  The previous special behaviour in the zero
	case be accomplished by passing a divisor of one.
	
	Rename Grid_Generator::multiply to Grid_Generator::scale_to_divisor.
	Correct the description of this method.
	
	Leave the factor normalization in Grid_Generator::is_equivalent_to as
	the only normalization, as sign normalization would only be required
	if divisors could be negative.
