length equal to the number of cells in the model, assign my colors, and
then display.  The problem I'm having is with the ExodusIIReader data
structure.

1) I understand the ExodusIIReader is, well, a reader -- it will generate
the data blocks, it's not actually representing the data.  But I don't get
how to access at the generated data.  Say I have a single block of elements
called 'hexes' with cell data 'stresses', how do I access that cell data in
the programmable filter?

2) Where should I insert the new array of rgb colors in the filter output
so that I can display them?  (Answering 1 may answer this equation).

Thanks,

Mark
