        public CRFOptimizableByGradientValues​(CRF crf,
                                              Optimizable.ByGradientValue[] opts)
        crf - CRF whose parameters we wish to estimate.
        opts - Optimizable.ByGradientValue objective functions. Parameters are estimated by maximizing the sum of the individual objective functions.
