Relating feeds and items

Now you'll model a one-to-many relationship between feeds and items, so that each feed has multiple items, and each item has a single feed.

Note: Another way to model this relationship would be to model RSSFeed as a subentity of WHTag which would implement the WHTaggable and WHIndexable interfaces. Creating resource types which can be used to tag other resources is a very powerful technique, but beyond the scope of this tutorial.
