returns the relative position of point test to the oriented circle defined by p, q and r.
The order of the points p, q and r is important, since it determines the orientation of the implicitly constructed circle.
If p, q and r are collinear, the circle degenerates in a line. CGAL::ON_ORIENTED_BOUNDARY is returned if test is also collinear or if two points are identical, otherwise, side_of_oriented_circle(r, q, test, p) is returned.
