This gem implements flexible time-ordered activity feeds commonly used withing social networking applications. As events occur, they are pushed into the Feed and distributed to all users that need to see the event. Upon the user visiting their "feed page", a pre-populated ordered list of events is returned by the library. Typically the data stored in the feed is a short-hand condensed variant of models, but it can also be a fully Marshalled objects, or JSON serializations.
