--Attack Script for Turtles in Minecraft
--This is an extremely simple attack script for the Melee Turtle in Minecraft. It will attack
-- whatever is in front of it every second or so. If it hasn't attacked anything in a predetermined
-- amount of time, the script will automatically exit, which lessens CPU load. Yay!
