Multistep methods like BDF or Runge-Kutta methods with FSAL property require restarting the solver in the event of
discontinuities. These discontinuities may be introduced as a consequence of explicitly modifications to the solution
vector (which PETSc attempts to detect and handle) or problem coefficients (which PETSc is not able to detect). For
the sake of correctness and maximum safety, users are expected to call TSRestart() whenever they introduce
discontinuities in callback routines (e.g. prestep and poststep routines, or implicit/rhs function routines with
discontinuous source terms).
