/** vtkOBJWriter - Write a Wavefront OBJ (ASCII) file. The core of this class
* was taken from vtkOBJExporter. The goal is to make it follow the standard
* "writer" syntax that is present for the rest of the VTK writers (vtkPLYWriter, etc).
* It only saves the geometry (vertices, lines, polylines, strips) with normals and tcoords (if any).
* It does not write triangle strips properly.
