code: public static Feature getFeature(PCM pcm, String ftName) {
  
  
          List<Feature> fts = pcm.getConcreteFeatures();
          for (Feature ft : fts) {
              if (ft.getName().equals(ftName)) {
                  return ft;
              }
          }
          return null;
  
      }
docs: of course this is weird to put such methods as an helper/utility
  alternatives are to consider putting such facility as part of PCM class
  @param pcm
  @param ftName
