// .NAME vtkUnstructuredGridReader - read vtk unstructured grid data file
// .SECTION Description
// vtkUnstructuredGridReader is a source object that reads ASCII or binary 
// unstructured grid data files in vtk format. See text for format details.
// .SECTION Caveats
// Binary files written on one system may not be readable on other systems.
