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)
