def __init__(self, fileobj):
self.fileobj = fileobj<EOL>self.mardata = mar.parse_stream(self.fileobj)<EOL>
Initialize a new MarReader object.

        Note:
            Files should always be opened in binary mode.

        Args:
            fileobj (file object): A file-like object open in read mode where
                the MAR data will be read from. This object must also be
                seekable (i.e.  support .seek() and .tell()).
