Prevent Duplicate Item()s From Being Added to Table #11

Closed theopak closed 11 years ago

Right now, duplicate Item() objects are saved to the sqlite3 table. This should not happen. An error should be raised if more than one Item() is to be added at a given loc, which represents the unique physical location of the shelf.
