      What to do here:

      load() reads the appropriate records to determine if this is an
      interior or exterior cell. The old D code should be straight
      forward to port here. Unlike the lists above, this struct
      contains two lists, one for each cell type. We will have to hack
      around again to get good indexing of exterior cells, but I think
      a hash thingie like we did in D will work. An alternative is
      just a map<map<>>, so we can do ext_cells[X][Y].whatever. Hmm, I
      think I like that better actually.
