CGAL::side_of_oriented_sphere

template <class ForwardIterator>
Oriented_side	side_of_oriented_sphere ( ForwardIterator first, ForwardIterator last, Point_d<R> p)
		returns the relative position of point p to the oriented sphere defined by the points in A = tuple [first,last) The order of the points in $$A is important, since it determines the orientation of the implicitly constructed sphere. If the points in $$A are positively oriented, the positive side is the bounded interior of the sphere. Precondition: A contains $$d+1 points in $$d-space. Requirement: The value type of ForwardIterator is Point_d<R>.
