cekees/fix moving mesh

- fixes hotstart capability
- fixes poor scaling when partitioning from tetgen files
- adds petsc logging in partitioning from tetgen files
- modifies Eisenstat-Walker adpative tolerance selection, but that needs  more work on a new branch
- took out the subdomain divergence  print statement. The max  over all elements in the simulation is logged.
@ahmadia and/or @mfarthin , can you please review this?
Okay, thanks for explaining.  That's ugly, and the only thing we can do is add assertions when we create the files that our index can be reflexively written to sprintf("%g") and read back.
