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?
these need more work, so am postponing anything on this until #137 is addressed
