 matrix_dataset::get_histo_info
        Return information relating to the histograms of a matrix
        dataset.

 Usage:
        info=dsref -> get_histo_info(<keys>)

 Keywords:
        index   int     Set this key to return properties for just one
                        stream rather than for all streams.
        count           If set, then return how many streams there are.
        names           If set, then return the names of the streams.
        species         If set, then return the names of the channels.
        references      If set, then return the object references (use
                        with care, destroying the objects will break
                        the whole dataset).
        frames          If set then return the frame number to which
                        the histogram applies
        directions      If set then return the histogram directions.
