Description: Provides an interface for quantitative-genetic models in
        'R', backed by the 'HSquared.jl' engine for 'Julia'. Fits
        Gaussian pedigree animal models by restricted maximum
        likelihood, using average-information restricted maximum
        likelihood (AI-REML; Gilmour et al. (1995)
        <doi:10.2307/2533274>) for the univariate model. Returns
        heritability, variance components, breeding values, and
        covariance and correlation matrices for multivariate models.
        Formula and pedigree validation can run without 'Julia'. Model
        fitting requires a local 'Julia' and 'HSquared.jl'; use
        hs_control(engine = "validate") to preview the model contract
        without fitting. What you may report is listed on the package
        article 'Can I fit and report this?', not in
        validation_status(), which is a developer evidence table.
        Model-specific restrictions are documented in that article.
        Uncertainty intervals are not coverage-calibrated.
