// .NAME vtkUnstructuredGridToReebGraphFilter - generate a Reeb graph from a
// scalar field defined on a vtkUnstructuredGrid.
// .SECTION Description
// The filter will first try to pull as a scalar field the vtkDataArray with
// Id 'fieldId' of the mesh's vtkPointData.
// If this field does not exist, the filter will use the vtkElevationFilter to
// generate a default scalar field.
