[Paraview] Spreadsheet display of Field Data?

[Cory Quammen]

Ah, never mind. I forgot to set a name for the array.

If I add

bestDimensionsArray->SetName( ... );

the field data array shows up as expected.

It seems like you should still be able to see the array values if the
array doesn't have a name, though.
