Photosynthesis... kinda

Just a random little script to make a prim expand and contract throughout the SL day, based on the amount of daylight and non-daylight the prim recieves. It also keeps the percent of volume from the max of 10 cubic meters ( I think I did the math right for it *crosses fingers*). I tried to keep it pretty simple and kinda random. Enjoy.
