Available patches

• fwbw_derivative switches the default spatial derivative from continuous to forward/backward difference.
  This generally reduces spurious oscillations in the result as the spatial accuracy of the derivative is then compatible with the underlying solution grid.
• petsc3.7 adapts to API changes introduced between PETSc 3.6.x and 3.7.x for setting PETSc options.
  Use this patch if your system runs PETSc 3.7.x.
