lling ``feed``, you can check the value of the ``done``
        attribute to see if you need to continue feeding the
        ``UniversalDetector`` more data, or if it has made a prediction
        (in the ``result`` attribute).

        .. note::
           You should always call ``close`` when you're done feeding in your
           document if ``done`` is not already ``True``.
