Revise paste Stripminer2.0+

-- Strip Mining Program V2.0.1 --
-- Includes anti-gravel protocol --
-- Mines until full, then terminates --
-- Connects to central monitor to relay inventory information --
-- Version 2 introduces a more automated algorithm, allowing for deposition of items once full and returning to mining

-- Tunnels are always two wide, 3 high in current version -- 
-- use "label set MiningTurtleX" to name turtles, and set "chn" to the same number
-- pastebin get Cfdm64bB mine

-- Config -- 
ver = "V2.0.1"
Mside = "left" -- set to whatever side the modem is on the turtle
chn = 1 -- set to channel you want to transmit on
