Next improvement on the decay script:

// composter script by eteam vers 2.1
//mod from Growth Script
//By Floog Stuart
//Some parts of the script taken from Cid Jacob's Photosynthesis Script.
//
//Makes a prim shrink along its longest side (when the sun is out). Starts decaying when touched.
//If you edit this script please give credit to Floog Stuart and Cid Jacob and eteam.
