Module containing the UniversalDetector detector class, which is the primary
class a user of ``chardet`` should use.

    The ``UniversalDetector`` class underlies the ``chardet.detect`` function
    and coordinates all of the different charset probers.

    To get a ``dict`` containing an encoding and its confidence, you can simply
    run:

    .. code::

            u = UniversalDetector()
            u.feed(some_bytes)
            u.close()
            detected = u.result

        Reset the UniversalDetector and all of its probers back to their
        initial states.  This is called by ``__init__``, so you only need to
        call this directly in between analyses of different documents.

        Takes a chunk of a document and feeds it through all of the relevant
        charset probers.

        After calling ``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``.

        Stop analyzing the current document and come up with a final
        prediction.

        :returns:  The ``result`` attribute, a ``dict`` with the keys
                   `encoding`, `confidence`, and `language`.
