Coupling Stokes via Nitsche

Registered by Andre Massing

Implement a first example of coupling two Stokes equations on overlapping meshes. This is the first step towards a chimera like method for FSI problems.

Whiteboard

As a first and simple approach, a stabilized Stokes element should be used. Take P1-P1 + \alpha h^2 gradient(p) * gradient(q)
(with adapting rhs to make it consistent)

Advantages:
-Easy to implement simple Stokes with tabulate_tensor functions has already been added (but needs revision)
- Stabilizing term is mainly just a copy paste from the poisson case.
