this was an early project with Sandia to optimize the reordering of cell indices for data locality.
<div><br>
</div>
<div>this is definitely something that we will have to revisit, but we would want to rethink how we connected to zoltan anyway.</div>
<div><br>
</div>
<div>so i think removing the connection is fine.</div>

I've not heard any objections to removing the Zoltan code, but just in<br>
case folks were particularly busy last week, I'll wait until later this<br>
week before starting to remove this code from the trunk.<br>
