/**
* @class vtkPointSetToLabelHierarchy
* @brief build a label hierarchy for a graph or point set.
*
*
*
* Every point in the input vtkPoints object is taken to be an
* anchor point for a label. Statistics on the input points
* are used to subdivide an octree referencing the points
* until the points each octree node contains have a variance
* close to the node size and a limited population (< 100).
