Haskell Photon Mapper Released to Hackage

I've now uploaded my Haskell photon mapper and raytracer to hackage. It is listed as a package called "crocodile" (named after my son's current obsession with crocodiles!).

It's all working on the Cornell box. It's pretty memory hungry, and has a few self-declared things to fix (eg irradiance gradients), but it's out there to play with.

Enjoy.
