Log message: In is_included_in merge some BE_LAZY=0 code into the BE_LAZY=1 case, and check if `x' is empty after minimization when BE_LAZY is 0. In minimize() call simplify instead of update_generators and update_congruences, where possible. Reduce all update_congruence calls to account for the fact the resulting grid always contains at least one point.
