[vtkusers] Specifying cells with names

[David E DeMarle]

Try adding a vtkStringArray
(http://www.vtk.org/doc/release/5.0/html/a02052.html) to the
vtkPolyData's vtkCellData arrays. Assuming the older vtk format
readers and writers respect that data type then you should be all set.
If not, try the newer vtk xml file format readers/writers they most
likely do.
