      public void operate​(Score score, SelectionBuffer selectionBuffer)
      Implement this method to do whatever you want to the Vector of Note accessible at selectionBuffer
       
       
             Example:
        
             // transpose pitch up or down by adding a variable called "interval" to its pitch
             public void operate(SelectionBuffer selectionBuffer) {
              for (Enumeration e=selectionBuffer.elements(); e.hasMoreElements(); ) {
                      Note note = (Note)e.nextElement();
                      if (!note.isRest()) {
                              // get pitch data, transpose it, and set it again
                              note.setPitchData(note.getPitchData()+interval);
                              // Use NoteFactory to recalculate staff level, accidental, and stem direction
                              NoteFactory.setLevelPitch(note, note.getPitchData());
                      }
              }
             }
