Operations
A model of this concept must provide:
Orientation	operator() (const Kernel::Point_3 &p, const Kernel::Point_3 &q, const Kernel::Point_3 &r, const Kernel::Point_3 &s)
	returns CGAL::POSITIVE, if s lies on the positive side of the oriented plane h defined by p, q, and r, returns CGAL::NEGATIVE if s lies on the negative side of h, and returns CGAL::COPLANAR if s lies on h.
Orientation	operator() (const Kernel::Vector_3 &u, const Kernel::Vector_3 &v, const Kernel::Vector_3 &w)
	returns CGAL::POSITIVE if u, v and w are positively oriented, returns CGAL::NEGATIVE if u, v and w are negatively oriented, and returns CGAL::COPLANAR if u, v and w are coplanar.
Orientation	operator() (const Kernel::Sphere_3 &s)
	returns the orientation of the sphere s.
