Description: Computes Laplace-approximate maximum likelihood for
        hierarchical and latent Gaussian models. A formula interface
        specifies observation densities (e.g. Gaussian, negative
        Binomial), fixed effects, and random terms (independent
        effects, smoothing terms). Customized response distributions
        and models for random effects can be specified through a
        low-level interface or by writing interoperable packages.
        Derivatives are computed using automatic differentiation with
        'CppAD', and used in trust region optimization to find modes of
        random effects. Derivatives of the Laplace approximation of the
        log-likelihood are computed using third order contractions and
        is compatible with custom atomics. The approach follows
        Kristensen, Nielsen, Berg, Skaug, and Bell (2016)
