Log message: In set_empty make con_sys false. Add a zero dimension universe case to max_min. Take out an old topology comment. In construct(ccgs) insert the integrality congruence when the dimension is greater than zero, and only check for false congruences in dimension zero when there are two or more columns in the given congruence system. In the box constructors and construct(const_gs,bool) call set_empty instead of setting the empty flag directly. In get_covering_box add a zero dimension check and set the box empty when the grid is empty. In shrink_bounding_box add a zero dimension check and take out a redundant check for rows in the generator system.
