Kernel::LessRotateCCW_2

bool	fo.operator() ( Kernel::Point_2 p, Kernel::Point_2 q, Kernel::Point_2 r)
		returns true iff the three points p, q and r form a left turn or if they are collinear and the distance of $$q to $$p is larger than the distance of $$r to $$p, where $$p is the point passed to the object at construction. Precondition: $$p does not lie in the interior of the segment $$rq, i.e. $$p is an extreme point with respect to $${p,q,r}.
