Description: Extends classical linear and quadratic discriminant analysis
    by incorporating permutation-group symmetries into covariance matrix
    estimation. Methods based on the 'gips' framework identify and impose
    permutation structures that regularize covariance estimates and improve
    stability and interpretability for symmetric or exchangeable features.
    The package provides pooled and class-specific covariance models,
    including multi-class variants with shared or independently estimated
    symmetry structures. The underlying methodology is described by
    Graczyk et al. (2022) <doi:10.1214/22-AOS2174> and Chojecki, Morgen,
    and Kołodziejek (2025) <doi:10.18637/jss.v112.i07>.
