serialize_attributes(format, *columns)

Create instance level reader that deserializes column values on request, and instance level writer that stores new deserialized values. If format is a symbol, it should correspond to a previously-registered format using register_format. Otherwise, format is expected to be a 2-element array of callables, with the first element being the serializer, used to convert the value used by the application to the value that will be stored in the database, and the second element being the deserializer, used to convert the value stored the database to the value used by the application.
