Changes  view on Meta::CPAN

 - Forgot to note a dependency on Algorithm::NaiveBayes in version
   0.05.  Fixed.

 - AI::Categorizer class wasn't loading AI::Categorizer::KnowledgeSet
   class.  Fixed.

 - Fixed a bug in which the 'documents' and 'categories' parameters to
   the KnowledgeSet objects were never accepted, claiming that it
   failed the "All are Document objects" or "All are Category objects"
   callbacks. [Spotted by rob@phraud.org]

 - Moved the 'stopword_file' parameter from Categorizer.pm to the
   Collection class.

 - Feature selection is now handled by an abstract FeatureSelector
   framework class.  Currently the only concrete subclass implemented
   is FeatureSelector::DocFrequency.  The 'feature_selection'
   parameter has been replaced with a 'feature_selector_class'
