[vtkusers] get all unstructured grid data from vtk

[awa5114]

Hello,

I am a new vtk user in python. I have an unstructured grid vtk file
containing the following:

ASCII
DATASET UNSTRUCTURED_GRID
POINTS       96 float
CELLS       96     192
CELL_TYPES       96
POINT_DATA       96
VECTORS vector1 float
VECTORS vector2 float
etc

I would like to, using the vtk library available in python, obtain the
values of the vectors for ALL my points as a python or numpy list. I am
toying with the following example in the vtk library website

https://lorensen.github.io/VTKExamples/site/Python/IO/UnstructuredGridReader/

It's a nice example that shows some wicked functionality. But that's useless
to a new end user like me who needs to accomplish simple data extraction and
functionality. Could anyone please provide some additional insight on how
this can be accomplished? 

Thanks
