Added a test case to check the correctness of k_bar in the SU stabilisation term.
Updated the path to the mesh file.
Assign the initial condition to self.solution as well.
Made the initial condition for Velocity equal to the exact solution.
Added contact details and author list.
Updated the section heading in the README.
Remove a section marker.
Improved a schema comment for the 'viscosity' option.
Added the .msh files for the MMS test.
When checking for a steady-state, also consider the Velocity field.

Also, set up a P1 function space for the coordinate field.
Made the MMS test more rigorous.
Added a comment about the double dot product.
Fix the test tolerances.
Generalised the steady-state calculation.

Also changed to the form of the stress tensor to grad(u) + grad(u)^T.
Use the full stress form for the stress tensor.
Updated the swe_mms_p2p1_quadratic_drag test to use the full stress tensor.
Removed the .py file generated by sage.
Removed an old function from the .sage file.
