BALL_GRID is a C library which generates a grid of points within the interior of an arbitrary ball in 3D.
The library allows the user to define an arbitrary ball by choosing its radius and center. The user also choose N, the number of subintervals into which a horizontal radius line will be subdivided. It then returns the gridpoints defined by that choice.
