[vtkusers] Get/Set values in scalar data

[John Haiducek]

Seb,

Thanks for the tip. I noticed the methods GetTuple1, GetTuple2, etc.,
but I was confused about the relationship between tuples and arrays. If
scalar array values are found in Tuple 1, are the others used for
elements of vector/tensor data, or for some other purpose?
