- Major improvements to NaiveBayes - it now gives results on par with
(slightly better than, actually) the Naive Bayes results in Yang's
"Re-Examination" paper.
- Corrected a floating-point underflow problem in NaiveBayes that
occurred with long documents
- When categorizing, NaiveBayes now correctly skips words that
weren't in any training documents.
- Added the threshold() accessor method to NaiveBayes
- Fixed a crash that occurred when no stopwords were specified
- Improved the formatting of the output for AI::Categorize::Evaluate
