ComputerCraft Turtle Obsidian maker

-- OBSIDI-BOT !!!
--
-- This will only work in my particular set up. Just here for your reference.
-- I have two chests, one where the turtle picks up buckets of lava, another where it deposits the empty
-- bucket and block of obsidian. It will stop and reboot when the lava runs out.
