|-snes_ms_type||- type of multi-stage smoother|
|-snes_ms_damping||- damping for multi-stage method|
Multi-stage smoothers should usually be preconditioned by point-block Jacobi to ensure proper scaling and to normalize the wave speeds.
The methods are specified in low storage form (Ketcheson 2010). New methods can be registered with SNESMSRegister().
