[Users] Cell centered and Refluxing

The thorn LSUDevelopment/Refluxing contains a sample static_tov.par in
three versions:

1. static_tov.par   the original, vertex centered case
2. static_tov_cc.par   with vertex centering
3. static_tov_cc_rf.par   with vertex centering and refluxing

If you diff static_tov.par and static_tov_cc.par, you should see what
changes are necessary. These are probably related to setting up the
coordinates and the extent of the simulation domain, as well as
choosing the interpolation orders correspondingly. Note that there are
no cell-centred ENO interpolators yet, so you'll have to use linear
interpolation for hydrodynamics.
