  """KD tree data structure for searching N-dimensional vectors.
  
  The KD tree data structure can be used for all kinds of searches that
  involve N-dimensional vectors. For example, neighbor searches (find all points
  within a radius of a given point) or finding all point pairs in a set
  that are within a certain radius of each other. See "Computational Geometry:
  Algorithms and Applications" (Mark de Berg, Marc van Kreveld, Mark Overmars,
  Otfried Schwarzkopf).
