// .NAME vtkPointSetToLabelHierarchy - build a label hierarchy for a graph or point set.
//
// .SECTION Description
//
// 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).
