// .NAME vtkGDCMPolyDataReader - read DICOM PolyData files (Contour Data...)
// .SECTION Description
// For now only support RTSTRUCT (RT Structure Set Storage)
// .SECTION TODO
// Need to do the same job for DVH Sequence/DVH Data...
// .SECTION Warning
// When using vtkGDCMPolyDataReader in conjunction with vtkGDCMImageReader
// it is *required* that FileLowerLeft is set to ON as coordinate system
// would be inconsistent in between the two data structures.
//
// .SECTION See Also
// vtkGDCMImageReader vtkGDCMPolyDataWriter vtkRTStructSetProperties
