[WIP] - Computercraft/Galacticraft Rocket Silo Launch System

--[[
Galacticraft Rocket Launching System V1
This program is designed for use in Tekkit (Galacticraft, MineFactory Reloaded*, & Computercraft mods required)

*or any mod that uses colored channels for redstone wiring (e.g. bundled cables from "ProjectRed - Transmission")

Wiring Guide:
(set the air lock controllers to open on redstone signal - Inverted)
Outputs:
    Air Locks:
        White Channel: Main Air Lock
        Orange: Rocket 1
        Magenta Channel: Rocket 2
        Light Blue Channel: Rocket 3
        Yellow Channel: Rocket 4
        Lime Channel: Rocket 5
        Pink Channel: Rocket 6

    Launch Controllers:
        Gray Channel: Controller 3
        Light Gray Channel: Controller 6

Important: Please create a program called .config on the computer. Put anything into line 1 of it and save it. This will serve as a storage of the air lock's state. This will get overwritten as the air lock cycles. It defaults to an oxygen sealed state (inner air lock opened, outer air lock sealed)
