Comment (by simonpj):
How do I run it to show the performance differences? I found 'main' in
`Viewer`, but could not run:
{{{
time ./viewer-6.10
Geometry []
viewer-6.10: Viewer.hs:(128,0)-(129,29): Non-exhaustive patterns in
function cell_size_2D
real 0m0.086s
user 0m0.068s
sys 0m0.018s
bash-3.2$
}}}
