Kernel::SideOfOrientedSphere_3

A model for this must provide:

Oriented_side
fo.operator() ( Kernel::Point_3 p,
Kernel::Point_3 q,
Kernel::Point_3 r,
Kernel::Point_3 s,
Kernel::Point_3 t)
returns the relative position of point t to the oriented sphere defined by p, q, r and s. The order of the points p, q, r, and s is important, since it determines the orientation of the implicitly constructed sphere. If the points p, q, r and s are positive oriented, positive side is the bounded interior of the sphere.

In case of degeneracies, ON_ORIENTED_BOUNDARY is returned if all points are coplanar. Otherwise, there is a cyclic permutation of the five points that puts four non coplanar points first, it is used to answer the predicate: e.g. side_of_oriented_sphere(q, r, s, t, p) is returned if q, r, s, and t are non coplanar.
