Went down a rathole trying to fix issue with the basic feature table in Select Features... always showing the scores category even if there were no scores-as-inputs.  Factored most of the model-type stuff in SelectFeatures into an object of class FeatureVocabulary.  Currently, the featureVocabulary mirrors all the changes to model-type stuff in SelectFeatures, but is not read from.
Merging bullshit.
