Updated package vignette and manual. Outlined the fact that choosing certain noise matrices for the algorithm results in joint distributions whose dependency structures can be characterized by corresponding copulas.
Upon the request from Brian D. Ripley, time-consuming examples are commented rather than wrapped by \donttest{}.
r-patched-solaris-x86 generated compile error due to the fact that the header file /usr/include/floatingpoint.h used variable name extended, which is re-declared in SimJoint/src/pcg/pcg_random.hpp. Changed extended to pcgExtended in the latter file.
Changed the random number generator from std::mt19937_64 to pcg64 <http://www.pcg-random.org/>.
Fixed a reported bug. Forgot to recover the normalized distributions before postSimOpt() returns.
Updated vignette.
