Fix source term if no grads present
Linearized Euler with non-uniform mean flow
- Warning, not tested yet with non-uniform mean flow
pydcm has lineuler
Cosmetics
PyDCM improvements

- CFL number is saved properly
- Navier-Stokes post-processing functions
- Restarting with different P-order
- Lists in definitions
Total pressure / Total temperature in post processing
PyDCM Shortcut for time
PyDCM: Remove previous PDE when creating new
PyDCM: NavierStokes 2D Square Cylinder case

Also Output and Restart executables
PyDCM Add Linearized Euler case Acoustic Pulse
