2006 version of MCLUST, by Fraley and Raftery
(Dept. of Statistics, University of Washington)

Version 3.0: New functionality added, including conjugate priors 
for Bayesian regularization. 
Backward compatibility is not guaranteed since the implementation of some 
functions has changed to make them easier to use or maintain.

Version 3.1: Most plotting functions changed to use color.
Mclust/mclustBIC fixed to work with G=1
Otherwise backward compatible with version 3.0.

Version 3.1-1: Default seed changed in sim functions.
model name check added to various functions. 
Otherwise backward compatible with version 3.0
