Minecraft - ComputerCraft - Turtle Extreme Farming

--Created by Wizard_Alfren--
--Created on 12 April 2020--
--Current as of 16 April 2020--
--This Lua script is for a Farming Turtle--
--1.  Turtle must be 1 block off the ground--
--2.  Turtle will start the farm on the 1st block at ground level in front if it--
--3.  A storage/chest needs to be placed behind the turtle to store the harvest--
--4.  Remember to clear the area of grass/objects--
--5a. You will be asked for the dimensions of the farm and then the type of seeds to plant--
--5b. Example:      Width: 9     Length: 18 --
--5c. The turtle's route is (length: 18) forward, and (Width: 9) rows to the right--
--5d. This script is able to use 1 of 3 types of seeds. (minecraft:wheat_seeds, minecraft:carrot, minecraft:potatoe)--
--6.  Seeds can be placed in the top row of the turtle's inventory (slots 1,2,3,4)--
--7a. Fuel can be placed in the bottom row of the turtle's inventory (slots 13,14,15,16)--
--7b. The accepted fuel types are minecraft:coal, railcraft:fuel_coke, ic2:coke--
