+multivariate normal using the @dfn{Geweke-Hajivassiliou-Keane} (GHK)
+simulator.  Unlike Gibbs sampling which can get stuck in one truncation
+sub-region depending on initial values, this package allows truncation based
+on disjoint regions that are created by truncation of absolute values.  The
+GHK algorithm uses simple Cholesky transformation followed by recursive
+simulation of univariate truncated normals hence there are also no convergence
+issues.  Importance sample is returned along with sampling weights, based on
+which, one can calculate integrals over truncated regions for multivariate
+normals.")
