#include <itkKdTree.h>
data structure for storing k-nearest neighbor search result (k number of Neighbors)
This class stores the instance identifiers and the distance values of k-nearest neighbors. We can also query the farthest neighbor's distance from the query point using the GetLargestDistance method.
