Corrected the latest refactoring - otherwise when called as a package no sphere model is returned (as no_spheres was not set in grid_to_spheres). Maybe latest tests were wrong as a stand alone script too - haven't checked. Also similar error with the radius. This is perhaps an inelligant way of solving the issue but it works.
