[vtkusers] how to make an array of vtkcellArray

[David E DeMarle]

The default constuctor isn't available because vtk objects are reference 
counted.

Instead of this:
  vtkCellArray *cell = new  vtkCellArray;
  ...
  delete cell;

use this:
  vtkCellArray *cell = vtkCellArray::New();
  ...
  cell->Delete();

and click on examples.
