First of all, thank you for this great package!

Just wondering if this package is still compatible with newer version of Ship API (version 26)?

In order to use the newer version of Ship API, I would need to replace the file "ShipService_v23.wsdl" that is in 'wsdl' folder with the file "ShipService_v26.wsdl". Just wondering if it will be sufficient to just specify wsdl_path in FedexConfig to point to the folder containing "ShipService_v26.wsdl" file and also override FedexProcessShipmentRequest class to setup _version_info and _config_obj object?

Otherwise, what should I do in order to use this package with the latest version of Fedex API?

Thanks in advance!
