Description: Fits functional generalized estimating equations for
        longitudinal functional outcomes and covariates using a
        one-step estimator that is fast even for large cluster sizes or
        large numbers of clusters. The package supports
        quasi-likelihoods derived from a range of distributions, with
        substantial simulations run for quasi-likelihoods derived from
        Gaussian, binomial, Poisson, negative binomial, Gamma and beta
        families. It supports common link functions and several working
        correlation structures. An optimized engine constructs cluster
        score and sensitivity statistics in one pass, provides
        coefficient-space Gaussian cross-validation, analytic-gradient
        fast cluster cross-validation, and an experimental
        sandwich-scaled working restricted quasi-likelihood selector.
        Internal compiled routines provide symmetric positive-definite
        Cholesky solves and exact tridiagonal precision operations for
        irregularly sampled continuous-time AR(1) working correlations.
        Uncertainty quantification is based on sandwich variance
        estimators and studentized wild cluster bootstrap procedures
        for cluster-robust pointwise intervals and optional
        simultaneous bands. The package implements methods described in
        Loewinger et al. (2025)
