Kernel::CompareY_2

Comparison_result	fo.operator() ( Kernel::Point_2 p, Kernel::Point_2 q)
		Compares the Cartesian $$y-coordinates of points p and q

Comparison_result	fo.operator() ( Kernel::Point_2 p, Kernel::Line_2 l1, Kernel::Line_2 l2)
		compares the $$y-coordinates of $$p and the intersection of lines $$l1 and $$l2, see (a) in the figure above.
Comparison_result	fo.operator() ( Kernel::Line_2 l, Kernel::Line_2 h1, Kernel::Line_2 h2)
		compares the $$y-coordinates of the intersection of line $$l with line $$h1 and with line $$h2, see (b) in the figure above.
