Examples of GeopositionComparator

no.priv.garshol.duke.comparators.GeopositionComparator
Comparator which compares two geographic positions given by coordinates by the distance between them along the earth's surface. It assumes the parameters are of the form '59.917516,10.757933', where the numbers are degrees latitude and longitude, respectively.
The computation simply assumes a sphere with a diameter of 6371 kilometers, so no particular geodetic model is assumed. WGS83 coordinates will work fine, while UTM coordinates will not work. @since 1.0
