-- ChangeLogs
-- 2.04 - Adding Left or Right Support
-- 2.05 - Changing Lot Code For Some Stable And Cleaner Code
-- 2.06 - Ops Forget Fuel Chcking Code after rewrtitting
-- 2.07 - Woops My Bad i wrote back() not Back()
-- 2.08 - Fixing Imputs
-- 2.09 - Forget That i change remove line of code since i use local function now
-- 2.10 - Minor error with back that it leave one block in wall
--    Change: Torch spacing to 8 from 10
-- 2.11 - Change: Right to left and Left to Right better understand
-- 2.12 - Add Stop Code when item are gone
-- 2.13 - i made big mistake i forget to end to new stop code
-- ToDoList
-- Add Code to place torch each time it starts
-- Add Fuel Code so can know almost how much fuel you need
-- Add second fuel slot if you go allout diggin
-- Mabye add code that make turtle make new line of tunnels
