added first draft for getting mass and stiffness jacobian. single_phase_gw/test_single_phase_gw.test_mass_and_stiff_jacobians has simple test that worked
I add my non-working docstring
minor alteration to documentation for linftyNorm
My test. The test produced failure!
add Diffusion_SIPG_exterior for SIPG weak boundary conditions
periodicDirichletConditions seems to be required for some cases but not in default_n
