> The class hierarchy for geometry claims that Vector is-a Point: https://commons.apache.org/proper/commons-math/apidocs/org/apache/commons/math3/geometry/Point.html
> This is mathematically incorrect, see e.g. http://math.stackexchange.com/a/645827
> Just because they share the same numerical representation, Point and Vector shouldn't
be crammed into a common class hierarchy.
