Kernel::ConstructOrthogonalVector_3

Kernel::Vector_3	fo.operator() ( Kernel::Plane_3 p)
		returns a vector that is orthogonal to the plane p and directed to the positive side of p.
Kernel::Vector_3	fo.operator() ( Kernel::Point_3 p, Kernel::Point_3 q, Kernel::Point_3 r)
		returns a vector that is orthogonal to the plane defined by Kernel::ConstructPlane_3()(p, q, r) and directed to the positive side of this plane.
