I'm a bit confused on the effect of cell_iterators (similar ones are cell_iterators_on_level and dof_handler.begin()) and mg_cell_iterators. In step16, begin_mg() is used when assembling multigrid, while in step56 we use cell_iterators rather than mg_cell_iterators. I think they both loop through all cells, active or not. In documentation the difference is mg_cell_iterators "return an iterator in their level-cell form". May some expert explain this a little further?
