Upgrade to FEniCS-2016.2.0

[bonh]

Do you plan an upgrade?

I am willing to help if it will work in parallel, see #99.

I think the issues are mainly due to the new syntax for RectangleMesh and BoxMesh in FEniCS 1.6. I have made pull requests.

@KristianE86 The parts of the Python interface I have been working on work for FEniCS 2016.2 and the dev version as well (these are: adapt, mesh_metric, refine_metric, detect_colinearity, patchwise_projection). Do you know about the rest? I think the test scripts were just not updated.

@bonh For the parallel, see my reply in #99

You are right - it works in serial using FEniCS 2016.2. I can probably contribute some patches for the examples if you wish.

Up-to-date FEniCS tests have been added in pragmatic/python/tests. The python files will probably need to be polished sooner or later. I am closing this issue.
