constructor

 * Locate nearest neighbours for a given point in space.

 * several points have the same distance.
 * @param distanceFunction A distance function for rectangle data. This parameter is optional,
 * passing a {@code null} will use the default distance function.
 * @param center the center point
 * @return The query iterator.
