Minor Description
There is a set of wrappers for vertex and edge input and output format classes that create a copy of the class and then calls certain methods using a modified context. The wrapped class is configurable, but setConf is never called on it. If a user creates their own vertex or edge input or output format that requires some special set-up, they cannot rely on the the setConf call to achieve this in all situations; it will work for unwrapped instances of the class but not for the wrapped class.
Thus for the wrapped classes there should be a setConf method that calls the super for the wrapper as well as setConf on the wrapped class.
