Run any example that uses assembled matrices (almost all of them) with
-pc_type ml.

It exposes the full multigrid hierarchy so all the usual options for PCMG
work.  ML-specific options are only available through the options database
(we don't have interface functions for all of them).  Run with

  -pc_type ml -help | grep pc_ml_

to see them.
