// .NAME vtkCMBPt123VelocityWriter - Writer to produce a PT123 Velocity VN
// based on a 3 component Data Array on a Data Set's Points
// .SECTION Description
// vtkCMBPt123VelocityWriter writes a Vector Field in ASCII.
// This can take a vtkMultiGroupDataSet as input, however in that case it uses
// the first leaf vtkDataSet.
