Thanks Sebastian. This one is much faster ---- 2.7s on my laptop with
the same dimensions/iterations.

It uses a better datastructures -- it only keeps track of points that
still need to be iterated --- very clever.
If I have time, I'll try to provide an equivalent Fortran version too,
for comparison.
