Minecraft Advanced Turtle Miner Program

--Follow the instructions below in order
--You will need, 1 advanced mining turtle, 1 bc factory mining well, 1 tesseract from thermal expansion, 1 ender chest from ender storage, 2 chicken chunks chunk loaders, and some fuel for your turtle
--Place down an advanced mining turtle high in the air away from obstacles facing some direction in a location of choice
--Place a mining well from bc factory in front of the turtle
--Place an ender chest from ender storage on top
--Place a thermal expansion tesseract on top of the mining well and let the turtle collect items
--Additionally put a fuel source inside of the turtles inventory like coal
--Put 1 chunk loader from chicken chunks in the turtles inventory and now place down a chunk loader behide the turtle
--Now run this program on the turtle
--If all of the above steps are followed correctly then the turtle should automatically move itself forward along with all its items
--It will also refuel itself constantly when its fuel level is below 50000 and also keep chunks loaded

--Changes in revision 1.3
--Added an additional nil check due to nil values somehow getting past the first nil check
--In game the turtle might find a few items that cause a nil index error thus the addition of the extra nil check
--Now if the turtle can't find an item it will continue to search for it and will not do anything until the item is provided
--Now if there is not enough fuel to operate the turtle will wait until enough fuel is provided
--End changes in revision 1.3

--Changes in revision 1.2
--Fixed typo in program causing the turtle not to turn
--The turtle will now work in a line and will not move outside of the line and will not place blocks outside this line
--End changes in revision 1.2

--Changes in revision 1.1
--Fixed memory issue caused by infinite recursion
--The chunk loader chould now be placed behind turtle rather than to the right
--End changes in revision 1.1
