--Turtle AutoBuilder v0.2
--Created by pokemonmegaman, 2012
--Uses files from BINVOX to create 3D models in game
--Better put alot of materials in this, because it uses a TON.
--
--Changelog
--v0.3: Turtle now returns to ground if it needs materials
--v0.2.1: Reversed build direction to stop mirroring, as well as future development
--v0.2: Stopped turtle from going up if there are no blocks to place, reducing build time signifigantly
--v0.1: Initial release

--there are also a couple of mods by BillBodkin
