CI started failing May 17th: ```bash coverage run --rcfile=.coveragerc python/demos/demo_contact_3D.py --gmsh --theta 0 --timing ``` which has coefficients equal to inf. Setting theta to be small (0.000001) resolves it.

Switch to spdlog and move some logging to debug mode

Also add some additional create_connectivity(tdim, tdim) calls prior to midpoint computations

dS integrals are not part of the integration kernels

1

Hello, As raised in [this post](https://fenicsproject.discourse.group/t/periodic-boundary-condition-with-dg-and-mpc/12957/6), `dolfinx_mpc` can not be used with DG discretization because "dS integrals are not implemented as part of the integration kernels" ([link to the code](https://github.com/jorgensd/dolfinx_mpc/blob/main/cpp/assemble_matrix.cpp#L608-L626))....

Can nedelec elements be used with Dolfinx MPC with perfectly matched meshes? How to do this?

Replace `create_cell_dofs_map` with `transpose_dofmap`
