StripMiner v0.1

Goals: Will strip mine up to 64 blocks away

-- Starting Location (Base)
local start_x, start_y, start_z = 634, 10, 1353

local x, y, z = start_x, start_y, start_z

-- Helpful function to handle checking inventory code.

-- Helpful function to handle getting back to base.

-- Logic: As long as we're inside of the min and maximums... we're okay.

	-- Step 1: Determine if the turtle found a block...
	if turtle.detect() then

-- Logic: When its low on fuel or is full... Go back to base by retracing steps.

	-- Take the current location and create a loop to go back...

	-- Determine if the turtle moved in the X or Z location.
