 Provides a data source for interfacing RestKit object loaders with Three20
 Table Views. The dataSource is intended to be used with an instance of
 RKObjectLoaderTTModel to perform a remote load of objects. The data source
 then allows you to turn your loaded objects into Three20 table items without
 a bunch of intermediary code.

 Registers a mapping from an object class to a custom UITableViewCell class. When the dataSource

 intermediary Table Items.
