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>.
