Description: Implements the U-smile methodology for threshold-free,
        class-specific comparison of probabilistic binary classifiers.
        The package quantifies prediction improvement and worsening
        separately for non-events and events using the Brier alteration
        (BA), relative Brier (RB), improvement proportion (I)
        coefficients, and relative likelihood ratio (rLR) coefficients,
        and provides U-smile, prediction improvement-worsening,
        receiver operating characteristic, and precision-recall plots.
        The original U-smile framework is described in Kubiak et al.
        (2024) <doi:10.1371/journal.pone.0303276>, its three-level
        extension for imbalanced binary classification in Wieckowska et
        al. (2025) <doi:10.1371/journal.pone.0321661>, and the
        likelihood-based extension in Wieckowska and Guzik (2026)
        <doi:10.1038/s41598-026-40545-z>.
