code: public static double computeEarthMoverAbsoluteDistance(Map<String, Double> h1, Map<String, Double> h2) {
          Signature s1 = EarthMoverDistanceWrapper.histogramToSignature(h1);
          Signature s2 = EarthMoverDistanceWrapper.histogramToSignature(h2);
  
          return JFastEMD.distance(s1, s2, 0.0);
      }
docs: probably only makes sense to compute this on CI
