public interface DistanceMeasure
```
Interface for measuring the distance of a (lon, lat) point to a reference (lon, lat) point, which is defined by the implementing class.
Let p and q denote two points en the Earth. Then, loosely speaking, any distance measure d(p, q) has to satisfy the following properties:
(1) d(p, q) = 0, if p = q
(2) d(p, q) > 0, if p ≠ q
