> A new implementation of Naive Bayes was introduced in .7.  The weight (theta) normalization
job was at least partially carried over but not fully implemented or enabled.  Weight normalization
does not effect simple NB or CNB however enabling it will allow for all NB implementations
in the Rennie et al. paper.
