Eliminated the flexfx scheme for calling global feature extractor functions through an array of function pointers. Deleted dead code I found as a by-product. This CL does not change BlobToTrainingSample or ExtractFeatures to be full members of Classify (the eventual goal) as that would make it even bigger, since there are a lot of callers to these functions. When ExtractFeatures and BlobToTrainingSample are members of Classify they will be able to access control parameters in Classify, which will greatly simplify developing variations to the feature extraction process.
