The class Random_points_on_square_2<Point_2, Creator> is an input iterator creating points uniformly distributed in the boundary of a square. The default Creator is Creator_uniform_2<Kernel_traits<P>::Kernel::RT,P>.

g is an input iterator creating points of type Point_2 uniformly
distributed on the boundary of the square with side length 2 a,
centered at the origin, i.e. ∀ p = *g: one
coordinate is either a or -a and for the
other coordinate c holds -a ≤ c < a .
A single random number is needed from rnd for each point.
