Add complex geometry fenics-fenics tutorial

[BenjaminRodenberg]

In #137 we decided to temporarily remove the complex geometry case. As soon as #125 is merged, we want to add it again. Here some todos/reminders:

• How do we want to call the case? partitioned-heat-conduction-complex?
• I copied the latest version from develop (05a0a44) into the new structure defined in Restructure tutorials #125 at 8107fbb on the branch i_147.

partitioned-heat-conduction-complex

sounds good to me. The "complex" not only means the geometry, but also different data mapping, time-dependent BCs etc.

I'll add a short specification similar to the one in #148 here, as well:

• Uses complex geometry (Circle + Plate with hole)
• Allows to swap Dirichlet and Neumann participants
• Uses Nearest Projection
• Allows to create non-matching meshes (with nearest neighbor this should still give us the exact solution, but I am not 100% sure)
• No subcycling (since this currently breaks the exact solution)
• Supports parallel runs.
• Supports time dependent flux & rhs (via parameter gamma)

Am I forgetting something here?

I decided to put the complex geometry case directly into #148, since it was simple enough to do everything in one single iteration. This allows us to close this issue as soon as #148 (and #125) is merged.

As per this comment all relevant PRs are merged and this issue is now resolved
