/**
 * An ItemSlot that appends probability information to the name of
 *  the item it contains. To use it, instead of putting an ItemStack
 *  or List in the data array, put an Object[] containing the item
 *  at index 0, and an Integer representing the probability at index
 *  1.
 *
 * Also worth noting, this class does not require any additional support
 *  within the rest of CraftGuide. If you copy it into a different package,
 *  and use that copy, it will function just fine with older versions of
 *  CraftGuide, as well as newer ones. It also shows how the API is set up
 *  to make that sort of extension possible.
