[vtkusers] vtk GetTuple

[David E DeMarle]

Work with the individual arrays in the field data.

Use vtkFieldData::GetNumberOfArrays() and vtkFieldData::GetArray(N) or
GetAbstractArray(N) and iterate.
Then you can use the GetValue signatures to access the data without
type conversion and possible loss of precision.
