Distance class

Calculates the distance between points.

Default algorithm is distanceWithVincenty, default radius is earthRadius

 final Distance distance = new Distance();

 // km = 423
 final int km = distance.as(LengthUnit.Kilometer,
    new LatLng(52.518611,13.408056),new LatLng(51.519475,7.46694444));

 // meter = 422592
 final int meter = distance(new LatLng(52.518611,13.408056),new LatLng(51.519475,7.46694444));
