Kernel::LessXYZ_3

bool	fo.operator() ( Kernel::Point_3 p, Kernel::Point_3 q)
		returns true iff the $$x-coordinate of $$p is smaller than the $$x-coordinate of $$q or if the are the same and the $$y-coordinate of $$p is smaller than the $$y-coordinate of $$q, or, if both $$x- and $$y- coordinate are identical and the $$z-coordinate of $$p is smaller than the $$z-coordinate of $$q.
