#include <CGAL/predicates_d.h>

template <class ForwardIterator>
Bounded_side side_of_bounded_sphere ( ForwardIterator first, ForwardIterator last, Point_d<R> p)
returns the relative position of point p to the sphere defined by A = tuple [first,last). The order of the points of A does not matter.
Precondition: orientation(first,last) is not ZERO.
Requirement: The value type of ForwardIterator is Point_d<R>.
