Given a set of points and a boundary, this function finds the position within or on the boundary that is most distant from the nearest point the set.
Some possible applications:
- Find the point farthest from a city, airport, radio mast, ....
- Find the point on an island farthest from the sea
Empirically, the order is closer to O(n) than to O(n log(n)).
