// .NAME vtkTreeLevelsFilter - adds level and leaf fields to a vtkTree
//
// .SECTION Description
// The filter currently add two arrays to the incoming vtkTree datastructure.
// 1) "levels" this is the distance from the root of the vertex. Root = 0
// and you add 1 for each level down from the root
// 2) "leaf" this array simply indicates whether the vertex is a leaf or not
//
// .SECTION Thanks
// Thanks to Brian Wylie from Sandia National Laboratories for creating this
// class.
