// .NAME vtkPolyLineToRectilinearGridFilter - filter that converts an input
// poly data with a single polyline to a 1-D regular rectilinear grid.
// .SECTION Description
// vtkPolyLineToRectilinearGridFilter converts an input polydata with single 
// polyline to a 1-D regular rectilinear grid. The output has additional point
// data indicating the arc-length for each point. Note that the Xcoordinates
// of the output are not related to those of the input. The input point 
// coordinates themselves are added as point data in the output.
