Me too! We need to look at all the io since much of it is broken in
parallel.

We need to settle on how to handle XML data. I favour (and I know Niclas
Janson does too) the VTK approach in which we have a 'master file' that
points to other XML files which contain portions of the vector/mesh,
etc. Process zero can read the 'master file' and then instruct the other
processes on which file(s) they should read in.
