[vtkusers] Are point clouds defined as Unstructured Points

[Amy Squillacote]

Hi Cally,

Are you using vtkPointSource to generate a point cloud? If so, the point 
cloud generated is a vtkPolyData. If you're creating the point cloud by 
hand, you could make it either a vtkPolyData or a vtkUnstructuredGrid.
