Description: Performs exhaustive or groupwise (backward elimination)
        variable selection for binary outcome prediction models using
        cross-validated Net Benefit as the optimization criterion. It
        supports predictor costs, restricted cubic splines, interaction
        terms, permutation importance, and parallel computation. It
        includes visualizations for model comparison and variable
        importance. References include Vickers AJ & Elkin EB (2006)
