baby patch/tweak: allow cell methods to take single cell
Cf. discussion in #176 -- taking on the small "(TODO: someone should probably fix that...)" from the tutorial re: grid's `get_cell_list_contents` requiring a list of cells even if it's just being passed a single cell.  It's a very easy fix, I'm on the case.  :-)
