// .NAME vtkStrahlerMetric - compute Strahler metric for a tree
// .SECTION Description
// The Strahler metric is a value assigned to each vertex of a
// tree that characterizes the structural complexity of the
// sub-tree rooted at that node. The metric originated in the
// study of river systems, but has been applied to other tree-
// structured systes, Details of the metric and the rationale
// for using it in infovis can be found in:
//
// Tree Visualization and Navigation Clues for Information
// Visualization, I. Herman, M. Delest, and G. Melancon,
// Computer Graphics Forum, Vol 17(2), Blackwell, 1998.
//
// The input tree is copied to the output, but with a new array
// added to the output vertex data.
//
// .SECTION Thanks
// Thanks to David Duke from the University of Leeds for providing this
// implementation.
