Log message: Always set zero dim universe via set_zero_dim_univ(). Insert a point in set_zero_dim_univ(). Create a correctly sized gen_sys in set_empty(). In the bounding box grid constructor move the generator system flag setting into the space_dim > 0 case. In the covering box grid constructor jump over the sorted flag clearing when an empty grid is produced. In construct(gs,) set space_dim before the empty test and set zero dim universe when required. In Grid(n,kind) set zero dim universe when required. Handle the zero dimension case in minimized_congruences(). In generators() just return gen_sys when the grid is marked empty, return the actual gen_sys for zero dim universe, ensure that gen_sys is up to date, and convert any parameters to points. In the zero dim cases of add_recycled_congruences_and_minimize and add_recycled_congruences set empty or zero dim universe only if required.
