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)
