question: public void deepSort ( int [ ] setFeatureSequence ) { featureSequence = setFeatureSequence ; numberOfLeaves = 0 ; tree = new MaryNode ( 0 , featureVectors . length ) ; sortNode ( 0 , tree ) ; }
target:  Launches a deep sort on the array of feature vectors. This is public because it can be used to re-index the previously read feature file.
