Sorry for the endless image spam people.

I got the grid-based version working, once I'd fixed a couple of really subtle
bugs in my geometry classes. I thought maybe I could get away with a 9x9x9 local
grid, but it turns out not. However, it still knocks spots off the old version -
calculates over 50 cells per second on my ageing laptop.

This image is based on a 20x20x20 master grid (8000 cells in total). I'm writing
out two .inc files, one for the points (about 200K for this example) and one for
the meshes (13.8MB). Quite reasonable I think. The meshes are fully minimized
mesh2 objects, but I'm probably using too many decimal places so that file size
could come down a bit. The rendering only took a couple of minutes.
