[Paraview] difference between types of mesh

[Francois Bertel]

Hi Dan,

vtkPolyData can deal with 0-D, 1-D, 2-D linear cells.

vtkUnstructureGrid can deal with all the types of cells that
vtkPolyData support+ 3-D linear cells and 1-D, 2-D,3-D non-linear
cells.

vtkPolyData is more compact and efficient for 0-D,1-D,2-D linear cells
than vtkUnstructureGrid.
