--For solar mining turtle.

--running arguments are x,y,z where;
--x = Number of cycles to move forward. (A cycle consists of 3 blocks on the axis of facing where the turtle occupies the central block) eg 10 cycles = 30 blocks
--y = the number of lines to mine to the left of the turtle.
--z = The starting height of the turtle (Used to calculate the fuel cost per cycle)
--
--Enderchest to store items in must be placed in the turtle's last inventory slot
