Description: Fits Bayesian models for species observed with imperfect
        detection: single-season and dynamic site occupancy (MacKenzie
        et al. (2002)
        <doi:10.1890/0012-9658(2002)083[2248:ESORWD]2.0.CO;2>),
        N-mixture abundance from replicated counts (Royle (2004)
        <doi:10.1111/j.0006-341X.2004.00142.x>), distance sampling,
        removal and double-observer counts, false-positive and
        time-to-detection occupancy, integrated models combining
        several data sources, multi-species and joint species
        distribution models, and a hurdle model for vegetation cover.
        Linear predictors take fixed, random, spatial and temporal
        effects. Each model supplies its observation likelihood to the
        'tulpa' engine, which fits it by Laplace approximation, by
        nested Laplace integration over the hyperparameters, or by
        Hamiltonian Monte Carlo with the No-U-Turn Sampler (NUTS) using
        automatic differentiation. Simulation, prediction and
        diagnostic functions (posterior predictive checks,
        leave-one-out cross-validation, simulation-based calibration)
        accompany each model.
