    This can be useful with a difficult mat file, containing unreadable
    variables.  This routine pulls the variables out in raw form and puts them,
    unread, back into a file stream for saving or reading.  Another use is the
    pathological case where there is more than one variable of the same name in
    the file; this routine returns the duplicates, whereas the standard reader
    will overwrite duplicates in the returned dictionary.

    The file pointer in `file_obj` will be undefined.  File pointers for the
    returned file-like objects are set at 0.

    Parameters
    ----------
    file_obj : file-like
        file object containing mat file

    Returns
    -------
    named_mats : list
        list contains tuples of (name, BytesIO) where BytesIO is a file-like
        object containing mat file contents as for a single variable.  The
        BytesIO contains a string with the original header and a single var. If
        ``var_file_obj`` is an individual BytesIO instance, then save as a mat
        file with something like ``open('test.mat',
        'wb').write(var_file_obj.read())``

    Examples
    --------
    >>> import scipy.io

    BytesIO is from the ``io`` module in python 3, and is ``cStringIO`` for
    python < 3.

    >>> mat_fileobj = BytesIO()
    >>> scipy.io.savemat(mat_fileobj, {'b': np.arange(10), 'a': 'a string'})
    >>> varmats = varmats_from_mat(mat_fileobj)
    >>> sorted([name for name, str_obj in varmats])

        Parameters
        ----------
        mdict : mapping
           mapping with method ``items`` returns name, contents pairs where
           ``name`` which will appear in the matlab workspace in file load, and
           ``contents`` is something writeable to a matlab file, such as a numpy
           array.
        write_header : {None, True, False}, optional
           If True, then write the matlab file header before writing the
           variables.  If None (the default) then write the file header
           if we are at position 0 in the stream.  By setting False
           here, and setting the stream position to the end of the file,
           you can append variables to a matlab file
