[vtkusers] VTK- Vectors visualization

[Berk Geveci]

You can always use the SetVectorsName in the reader. However,
this is inefficient since every time you read nth vector, all
n-1 previous vectors have to skipped by the reader. I would 
recommend using one file per field if you are interested in
efficiency (of course, then it is more work to maintain).

All these vectors are described in the same file and, they are  associated to a single data structures data points block
