Functions to perform n-dimensional numerical integration on n parameters with a multivariate normal prior distribution.
init.quad to generate a quadrature grid, and
eval.quad to evaluate the integral.
Evaluation is performed with Gauss-Hermite quadrature, with a prior distribution that can be specified to any multivariate normal.
Additionally, the grid can be adapted to any multivariate normal distribution - that is known to be close(r)
to the posterior distribution under evaluation.
