  // .NAME vtkvmtkPolyDataBoundaryExtractor - Extract boundary edges as poly lines.
  // .SECTION Description
  // This class identifies boundary edges and organizes them into poly lines based on connectivity. It also provides the output with a point data vtkIdTypeArray (set as active scalars) in which the ids of boundary points in the input dataset are stored.
