[Paraview] Enzo data

[George Zagaris]

Hi Matt,

This issue has been fixed, however, the
changes have not been merged yet with master.

They will be available soon if you can wait. Otherwise,
if you would like to try it out, I will be happy to push
my branch to gitorious for you to try it out.

Best,
George
