Scrap the whole thing?

I think I've hit a wall.  The ai-array is too complex.

The trouble is that this all requires a lot of local bookkeeping,
while using an object-oriented approach would avoid that.

Maybe it's time to look at it in a different way.

- Every node is a grid
- Grids can be constructed from grids (transposes?)
- The whole thing can be compiled to a stateless update function + explicit state objects.
