        public static Refiner loadInstance​(ADag dag,
                                           PegasusBag bag)
                                    throws TransferRefinerFactoryException
        Loads the implementing class corresponding to the value specified in the properties. If the package name is not specified with the class, then class is assumed to be in the DEFAULT_PACKAGE. The properties object passed should not be null.

        In addition it ends up loading the appropriate Transfer Implementation that is required by the refiner.

        Parameters:
        dag - the workflow that is being refined.
        bag - the bag of initialization objects
        Returns:
        the instance of the class implementing this interface.
        Throws:
        TransferRefinerException - that nests any error that might occur during the instantiation.
        TransferRefinerFactoryException
