The class Random_points_on_circle_2<Point_2, Creator> is an input iterator creating points uniformly distributed on a circle. The default Creator is Creator_uniform_2<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_2 uniformly
distributed on the circle with radius r,
i.e. |*g| == r . A single random number is needed from
rnd for each point.
