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>.
