Comparison_result	compare_xyz ( Point_3<Kernel> p, Point_3<Kernel> q)
		Compares the Cartesian coordinates of points p and q lexicographically in $$xyz order: first $$x-coordinates are compared, if they are equal, $$y-coordinates are compared, and if both $$x- and $$y- coordinate are equal, $$z-coordinates are compared.
