      public int compare(FeatureStructure fs1, FeatureStructure fs2)
      Compare two annotations. First compare by start position, where smaller start position means smaller annotation. If start positions are equal, compare by end position, where larger end position is smaller. Finally, compare by type code, arbitrarily. Does not compare feature values.
      Specified by:
      compare in interface FSComparator
      Parameters:
      fs1 - FS1.
      fs2 - FS2.
      Returns:
      -1, if FS1 is "smaller" than FS2; 1, if FS2 is smaller than FS1; and 0, if FS1 equals FS2.
