    Game of Life - 140byt.es

This uses the Haversine formula to calculate the great-circle distance between two points.
Usage

distanceLatLng (
  latitude1, longitude1 // first coordinates
  latitude2, longitude2 // seconds coordinates
  diameter // earth diameter (might be any unit)
)

// returns the distance in the specified unit
```

### Earth Diameter

* 2 * 6378.137 Kilometers
* 2 * 6378137 Meter
* 2 * 3963.190 Miles
