ELLIPSOID_GRID is a C++ library which generates a grid of points over the interior of an ellipsoid in 3D.
The library allows the user to define an ellipsoid by choosing the 3D coordinates of its center and the lengths of its three axes. The user also choose N, the number of subintervals into which the shortest radius will be subdivided. It then returns the gridpoints defined by that choice.
