DirtyDigger - Minecraft Strip Mine Program

-- Dirty Digger v0.72
-- + dropping torches between tunnels

-- Dirty Digger v0.71
-- + added digging in main tunnel if there are blocks in the way of starting new tunnels

-- Dirty Digger v0.7
-- + debugged support for parallel tunnels

-- Dirty Digger v0.6
-- + added support for parallel tunnels

-- Dirty Digger v0.5
-- + added support for regular chests

-- Dirty Digger v0.4
-- + dig, digUp, digDown functions that detect additional blocks to mine before moving on

-- Dirty Digger v0.3
-- + Added wall check and replace to fill in holes in the tunnel as its being mined.
-- + Adjusted checks at end of mining sequence so space check is before torch check to avoid conflicts with the two

-- Dirty Digger v0.2
-- + Auto return to starting position

-- Dirty Digger v0.1
-- + 3x3 tunnels
-- + enderchest storage
-- + auto torch (every 4 blocks)
-- + auto refuel (when below 10 fuel level)

-- Roadmap:
-- + Detect missing walls and replace
-- + Make sure enderchest and torches can't be placed in same block
-- + Parallel tunnels (left or right)
-- + Variable tunnel width
-- + Varible torch spacing
-- + Slots to define trash blocks
