This interface indicates if a file qualifies for ASCII translation. To
support customization of TAR translation, this interface allows the
programmer to provide an object that will check files that do not match the
MIME types file's check for 'text/*' types. To provide your own typer,
subclass this class and set the TarArchive's TransFileTyper via the method
setTransFileTyper().
