Interesting idea, but typical operations will be iterating along the
cells in a given row or column, so a 2d doubly-linked list would
probably work better than any sort of space-partitioning tree. But
then I lose easy random access to a cell. Vector(-of-vectors) and {[x
y] => cell} do seem like my best bets here.
