// Class for service that return a fully qualified name of a file that
// has been copied into local scratch, when given a URI specifying a
// desired file.  This inherits from the art::FileTransfer base class.
// Eventually, GeneralFileTransfer will replace this class; this ad-hoc
// concrete class is meant as an early-testing scaffold.
