--- Inventory Abstraction Library
-- Inventory Peripheral API compatible library that caches the contents of chests, and allows for very fast transfers of items between AbstractInventory objects.
-- Transfers can occur from slot to slot, or by item name and nbt data.
-- This can also transfer to / from normal inventories, just pass in the peripheral name.
-- Use {optimal=false} to transfer to / from non-inventory peripherals.
-- Now you can wrap arbritrary slot ranges
-- To do so, rather than passing in the inventory name when constructing (or adding/removing inventories)
-- you simply pass in a table of the following format
-- {name: string, minSlot: integer?, maxSlot: integer?, slots: integer[]?}
