Kernel::LessSignedDistanceToLine_2

bool	fo.operator() ( Kernel::Line_2 l, Kernel::Point_2 p, Kernel::Point_2 q)
		returns true if the signed distance from $$p and the oriented line $$l is smaller than the signed distance of $$q and $$l.
bool	fo.operator() ( Kernel::Point_2 p, Kernel::Point_2 q, Kernel::Point_2 r, Kernel::Point_2 s)
		returns true if the signed distance from $$r and the oriented line $$l defined by $$p and $$q is smaller than the signed distance of $$s and $$l. Precondition: $$p != q.
