* Replaces primary key with `RKEntityIdentifier` * Add support for use of compound keys for object identification * Refactor `RKConnectionMapping` to `RKConnectionDescription` and add support for connecting with multiple attributes * Clarify naming of representation key methods to better match naming conventions * Add type transformation support for object identification * Greatly expand test coverage for object identification * Drop the `NSEntityDescription` category * Simplify the `RKManagedObjectCaching` protocol * Add compound key support to the Fetch Request and In Memory Cache implementations * Replace Kiwi with Specta for tests where contexts are helpful for organization * Rename `defaultValueForMissingAttribute` to `defaultValueForAttribute`
