+A `transferor` is an address that has the right to transfer express lane controller rights on behalf an express lane controller. The reason to include this function (setTransferor) is so the express lane controller has a way to nominate an address that can transfer rights to anyone they see fit, in order to improve the reselling rights user experience.
