-====== LibTF.Inventory======
-**Inherits From:** [[libtf:documentation:api:persistentobject|LibTF.PersistentObject]]
-An Inventory is an object that contains other things.  An inventory is used to track items that a Person carries.  A different specialized inventory is used to track what Apparel a Person is wearing.  A trunk or bookshelf might use an Inventory to track what is held within on on it.  In a more traditional sort of location-based Twine IF, each location might even use an inventory to track what items the player can find or has dropped there.
