Kernel::LessSignedDistanceToLine_2

bool	fo.operator() ( Kernel::Point_2 p, Kernel::Point_2 q, Kernel::Point_2 r, Kernel::Point_2 s)
		returns true iff the distance of $$r to the oriented line through $$p and $$q, where $$p and $$q are the points passed to the object at construction, is smaller than the distance of $$s to this line. If both have the same distance, true is returned iff the distance of $$q to $$p is smaller than the distance of $$r to $$p, where $$p is the point passed to the object at construction.
