/** \class WeightedCentroidKdTreeGenerator
* \brief This class generates a KdTree object with centroid information.
*
* The KdTree object stores measurment vectors in a k-d tree structure
* that is a binary tree. The partition value is the median value of one
* of the k dimension (partition dimension). The partition dimension is
* determined by the spread of measurement values in each dimension. The
* partition dimension is the dimension has the widest spread. Our
* implementation of k-d tree doesn't have any construction or insertion
* logic. Users should use this class or the KdTreeGenerator class.
*
* This class is derived from the KdTreeGenerator class. The only
* difference between this class and the KdTreeGenerator class is that
* the nonterminal node type of this class is
* KdTreeWeightedCentroidNonterminalNode and that of the
* KdTreeGenerator is KdTreeNonterminalNode. Therefore, the public
* interface is identical to each other. The nonterminal node generation
* routines differ.
*
* To run this generator, users should provides the bucket size
* (SetBucketSize method) and the input sample (SetSample method). The
* Update method will run this generator. To get the resulting KdTree
* object, call the GetOutput method.
*
* <b>Recent API changes:</b>
* The static const macro to get the length of a measurement vector,
* 'MeasurementVectorSize' has been removed to allow the length of a measurement
* vector to be specified at run time. It is now obtained from the sample set
* as input. You may query this length using the function GetMeasurementVectorSize().
