* A {@link SingleDimensionValuesSource} for geotile values.
*
* Since geotile values can be represented as long values, this class is almost the same as {@link LongValuesSource}
* The main differences is {@link GeoTileValuesSource#setAfter(Comparable)} as it needs to accept geotile string values i.e. "zoom/x/y".
