Quarry script for ComputerCraft turtles.

This script aims to the most reliable and self-sufficient way for a mining turtle to dig a quarry with as little human supervision as possible.

Easiest way I know of installing quarry in your turtle, is to download the setup script from pastebin:

pastebin get LcrmJKAn setup

and then run it, it will download the scripts from this repository. Then just run quarry, there are a few flags you can specify:

quarry [-m] [-c]

-m indicates to use a modem to broadcast status messages. -c means to use only Charcoal as fuel, if you don't want it to consume any coal it mines. More flags and customization to come.

• Automatic refueling, using up coal as needed including coal mined from the ground.
• Inventory management such as item sorting and stacking, dropping out thrash such as cobblestone and dirt when inventory is full, and storing ores and treasures in a chest.
• Tries it's best to come back up when something goes wrong, so you don't have to jump into the pit to rescue the turtle if it gets stuck for instance.
• It digs 3 layers at once by digging forwards, up and down for fuel efficience.
• Optionally broadcasts messages over rednet, such as "Dropping thrash" or "Out of fuel", but it's currently unreliable and doesn't seem to work 100% of the time for me.

• Remember where it left off in a layer before going up to drop stuff in the chest, so when it comes back doesn't need to "restart" the layer.
• Proper rednet communication with maybe a proper monitor program that prints out a diagram of where the turtle is in real time, with options like "come back up".
• Option not to throw, or specifying what "thrash" is.
• Option to specify layer size, now hard coded as 16x16.
