  Description
  BallTree
  Class implementing the BallTree/Metric Tree algorithm for nearest neighbour search.
  The connection to dataset is only a reference.
  CoverTree
  Class implementing the CoverTree datastructure.
  The class is very much a translation of the c source code made available by the authors.
  For more information and original source code see:

  FilteredNeighbourSearch
  Applies the given filter before calling the given neighbour search method.
  KDTree
  Class implementing the KDTree search algorithm for nearest neighbour search.
  The connection to dataset is only a reference.
  LinearNNSearch
  Class implementing the brute force search algorithm for nearest neighbour search.
  NearestNeighbourSearch
  Abstract class for nearest neighbour search.
  PerformanceStats
  The class that measures the performance of a nearest neighbour search (NNS) algorithm.
  TreePerformanceStats
  The class that measures the performance of a tree based nearest neighbour search algorithm.
