/**
 * Redstone Circuit Control Code
 * <p/>
 * This should make everything possible what a Redstone Computer or BuildCraft Gate could do.
 * It is intended to use this similar to BC-Gates (for acquiring Data) and RP Logic Gates.
 * You could write an extremely specified and complex Logic Gate, which works only for you Setup, like
 * with ComputerCraft, but you would have to write an extra Mod to add that, as it doesn't work Ingame.
 * <p/>
 * One can make use of the fact, that ItemStacks can be stored as Integer, so that you can scan
 * Inventories for specific Items using that. Luckily the Buttons in the GUI enable Copy/Paste of
 * ItemID+MetaData to Integer, including the WildCard Damage Value when you use rightclick to place it.
 * You just need to use @GT_Utility.stackToInt(ItemStack aStack) to get it.
 * <p/>
 * All Functions run usually in a seperate try/catch Block, so that failed Logic won't crash the TileEntity.
