/**
* Player-run shop stock cabinet object.
* This object is used by player-run shops to store the shop's stock.
* Each cabinet will save its own inventory, and offers a method of
* splitting the stock up into smaller chunks. This will help prevent
* the Tarnach's experience where 650k of stock is being saved every
* time there is a change in the contents.
* This object should not be inherited by anything, but should be created
* by the player_shop storeroom.
