UniqueInventory (Salespoint 7.2.2.RELEASE API)

All Superinterfaces:

org.springframework.data.repository.CrudRepository<T,InventoryItemIdentifier>, Inventory<T>, org.springframework.data.repository.Repository<T,InventoryItemIdentifier>
```
public interface UniqueInventory<T extends UniqueInventoryItem>
extends Inventory<T>, org.springframework.data.repository.CrudRepository<T,InventoryItemIdentifier>
```
A UniqueInventory manages UniqueInventoryItems, i.e. only a single InventoryItem can exist per Product. This simplifies the lookup of the quantity available for a given Product to the lookup of a single UniqueInventoryItem.
Also, on Order completion, a UniqueInventoryItem can be updated and get its Quantity deducted based on the quantity of products ordered.
