CTPy-19 Classification statistics module - in prep for parallelization

Added shannon entropy, design space fraction occupied, class and mode richness to stats.  Still need to do IQV (and possibly other diversity measures).

 A separate script will have to do the class innovation interval times, since the model for how we process the data samples is different.
