Description: Build and apply symmetric and asymmetric moving averages
        (= linear filters) for trend-cycle extraction. In particular,
        it implements several modern approaches for real-time estimates
        from the viewpoint of revisions and time delay in detecting
        turning points. It includes the local polynomial approach of
        Proietti and Luati (2008), the Reproducing Kernel Hilbert Space
        (RKHS) of Dagum and Bianconcini (2008) and the
        Fidelity-Smoothness-Timeliness approach of Grun-Rehomme,
        Guggemos, and Ladiray (2018). It is based on 'Java' libraries
        developed in 'JDemetra+' (<https://github.com/jdemetra>), time
        series analysis software.
