TSGetSNES
Returns the SNES (nonlinear solver) associated with a TS (timestepper) context. Valid only for nonlinear problems.
Synopsis
#include "petscts.h"
PetscErrorCode TSGetSNES(TS ts,SNES *snes)
Not Collective, but SNES is parallel if TS is parallel
Input Parameter
Output Parameter
 snes   the nonlinear solver context

Notes
The user can then directly manipulate the SNES context to set various
options, etc. Likewise, the user can then extract and manipulate the
KSP, KSP, and PC contexts as well.
TSGetSNES() does not work for integrators that do not use SNES; in
this case TSGetSNES() returns NULL in snes.
