The ReadMe file say existing objects can be updated on import by calling the instance method '-rzi_updateFromDictionary:' on those objects, but no such method exists in the current implementation. (The missing method is described in the paragraph just before the heading 'Custom Mappings'.)
Existing objects will be updated if the user implements the class method '+ rzi_existingObjectForDict:' on the objects' class(es), but this requires the user to track such objects instead of letting existing objects identify themselves by calling the missing instance method.
