v0.6-12

NIMBLE is an R package for hierarchical statistical modeling (aka
graphical modeling). It enables writing general models along with
methods such as Markov chain Monte Carlo (MCMC), particle filtering
(aka sequential Monte Carlo), and other general methods.

This release is a maintenance release focused on bug fixes, including
fixing a numerical bug in the bootstrap filter and fixing an overly
aggressive check for random arrays in model building.
