o The EM algorithm has gained an extra argument 'classification',

o Parameters are now given proper names, following the glm() scheme
(e.g. '(Intercept)', 'x1', et cetera); with this, the show and summary
- methods have changed considerably and now produce more compact and more
- readable output. The summary method (for both fitted and unfitted
- models) now has an argument 'compact' (TRUE by default) that controls
- the presentation of the repsonse model parameters. The prior and
