The class Random_points_on_sphere_3<Point_3, Creator> is an input iterator creating points uniformly distributed on a sphere. The default Creator is Creator_uniform_3<Kernel_traits<P>::Kernel::RT,P>. The generated points are computed using floating point arithmetic, whatever the Kernel is, thus they are on the circle/sphere only up to rounding errors.

g is an input iterator creating points of type Point_3 uniformly
distributed on the boundary of a sphere with radius r,
i.e. |*g| == r . Two random numbers are needed from
rnd for each point.
