some findings:
- running 2nd order RK seems to work okay (but we need to use a smaller CFL because of instability):
./pyro.py compressible_rk rt inputs.rt compressible.temporal_order=2 vis.dovis=0 driver.cfl=0.4
- using reflect BCs top and bottom seem to keep it centered vertically, but there is some distortion
./pyro.py compressible_rk rt inputs.rt mesh.ylboundary=reflect mesh.yrboundary=reflect vis.dovis=0

This is a CFL issue. Running with CFL < 1/d (d = dimensionality) fixes it
