[vtkusers] Call for Examples!

[Bryn Lloyd]

Kenneth,

Regarding example:
http://www.cmake.org/Wiki/Create_a_surface_from_Unorganized_Points

The reason for the segmentation fault is that the vtkPoints is created 
in the function and returned. The smartpointer reduced its count to zero 
and deletes it.

I fixed the example. Now it first creates the vtkPoints. The actual 
values are inserted in the readPoints function.

Cheers
Bryn
