Represents the results of an Adapter's data operation. Ensures each adapter returns a consistent format to the data layer for further processing (caching, error handling, etc.).
NOTE: This entire object should be serializable (i.e. no functions or complex built-in objects) so the caching layer can retrieve the full Response on subsequent calls.
