Snake.tz - a very old sim where I modified walker.tz to have a snake morphology

I was going through some old folders and found this from an old version of breve and I figured there might be the off chance that someone would out of convenience want to try this one out rather than trying to make their own.
Disclaimer: this is from a while back so there is a lot of terrible code in there; its offered warts and all rather than throw it away and have noone potentially use it. Also, I'm using this as a starting point for a simulation incorporating python-neat and I will post results when I have them.
