iinla

This is an internal wrapper for iterated runs of <code>INLA::inla</code>.
For nonlinear models, a linearisation is done with
<code>bru_compute_linearisation</code>, with a line search method between each
iteration. The <code>INLA::inla.stack</code> information is setup by <code>bru_make_stack()</code>.

internal

Facilitates spatial and general latent Gaussian modeling using
integrated nested Laplace approximation via the INLA package (<https://www.r-inla.org>).
Additionally, extends the GAM-like model class to more general nonlinear predictor
expressions, and implements a log Gaussian Cox process likelihood for
modeling univariate and spatial point processes based on ecological survey data.
Model components are specified with general inputs and mapping methods to the
latent variables, and the predictors are specified via general R expressions,
with separate expressions for each observation likelihood model in
multi-likelihood models. A prediction method based on fast Monte Carlo sampling
allows posterior prediction of general expressions of the latent variables.
