"""models.py -- Contains DDBObject subclasses.

This module basically just imports DDBObject subclasses like Feed, Item, etc.
from other modules.  It exists as a central location that any other module can
import.

One reason this module exists is circular imports.  For example Item
references Feed and Feed refereces Item, which is a potential problem.  To get
around this, this module waits to import things until initialize() is called.
