Package-level declarations

Minecraft uses different numbering systems for slots in inventories. Depending on which methods are used each slot can have different indices. There are two main systems for numbering the slots in an inventory. One is used by the Container in GuiContainer classes and the other system is used when the inventory is accessed directly such as in InventoryPlayer.

This class was made to make the use of skyblock itemIDs easier for identifying items. The attributes are also meant to make it easy to group similar items such as shortbows or witherblades, so that those do not always have to be listed individually when it does not matter which one is used.
