Description: Performs repeated nested cross-validation for Cox
        Proportionate Hazards, Cox Lasso, Survival Random Forest, and
        their ensemble. Returns internally validated concordance index,
        time-dependent area under the curve, Brier score, calibration
        slope, and statistical testing of non-linear ensemble
        outperforming the baseline Cox model. In this, it helps
        researchers to quantify the gain of using a more complex
        survival model, or justify its redundancy. Equally, it shows
        the performance value of the non-linear and interaction terms,
        and may highlight the need of further feature transformation.
        Further details can be found in Shamsutdinova, Stamate,

        Algorithms to Boost Performance and Preserve Interpretability
        for Health Outcomes" <doi:10.1007/978-3-031-08337-2_15>, where
        the method is described as Ensemble 1.
