* Updates to the Core Data layer such that NSManagedObjectContexts now have a reference to the managed object store they belong to. * NSManagedObject instances can now return the managed object store they belong to. * Relaxed the coupling to the sharedManager present within the RKSearchableManagedObject class. * Expanded documentation of RKSearchableManagedObject
