Thanks Karen. I will incorporate the change in step (a) of compile.

For output on screen I do plan to clean it a bit. As usual, this first
phase was to get code ported/linked... and create README before today's
mirror deadline.

For viz., currently vtk files are written out and so next step (as of now)
is to viz. them and get a sense of what happened. I haven't planned any
exercises yet.

Thanks,
Onkar
