  print(Maidenhead.to_location('JN75xu32SP')); // 45.844271  15.947917
  print(Maidenhead.to_location('JN75XU32NV')); // 45.845313 15.946181
  print(Maidenhead.to_maiden(45.844271, 15.947917, 5));
  print(Maidenhead.google_maps_maiden('JN75xu32SP'));

    // 177.69963804384477 meters
  print(Haversine.distance_maiden('JN75xu32SP', 'JN75XU32NV'));

  var pos1 = Maidenhead.latlon(45.844271, 15.947917, precision: 5);
  var pos2 = Maidenhead.latlon(45.844271, 15.947917, precision: 5);
  var distance = pos1.distance_to(pos2);
  var bearing = pos1.bearing_to(pos2);
  print('distance: ' + distance.toString() + ' bearing: ' + bearing.toString());
  print('pos1 to pos2 distance: ' +
      Haversine.distance_maiden(pos1.grid, pos2.grid).toString());
