[vtkusers] Visualisation of cell-based data.

[Will Schroeder]

VTK supports cell data; it's just like point data except associated with 
cells. There are also filters to convert between cell data and point data 
(vtkCellDataToPointData and vtkPointDataToCellData) based on local 
averaging schemes. (You may need this: some filters e.g. contouring only 
work on point data). Some filters may operate on either cell or point data, 
the user has to specify (e.g., vtkThreshold).The readers and writers all 
support point and cell data as well.
