fix build failures with GCC 12 and without IPopt

use `getCommunication()` instead of `getCollectiveCommunication()`

This fixed the following error when building with GCC 12.1.0-8 (Debian):

```
/src/dune-gfe/dune/gfe/rotation.hh:225:42: error: invalid declarator before 'axis'
  225 |     Rotation<T,3>(Dune::FieldVector<T,3> axis, T angle)
      |                                          ^~~~
/src/dune-gfe/dune/gfe/rotation.hh:225:41: error: expected ')' before 'axis'

Enable more tests for the various TargetSpace classes

See merge request !93

This triggers bugs in the Rotation and RigidBodyMotion classes.

In particular, it triggers what Jonathan Youett fixed in the
never-merged merge request

  !2

These bugs are fixed in this commit, too:
* The RigidBodyMotion class gets a `log` method
* The Rotation<3>::log method now returns EmbeddedTangentVector
  instead of TangentVector.

It was TangentVector whereas it should have been
EmbeddedTangentVector.

Calling log(a,b) returned a-b instead of b-a.

Also, enable unit tests for the RealTuple class.  The current test
will not trigger the bug in the log method: that will come shortly.

Finally, this commit is the first that mentions its user-facing
changes in the newly introduced CHANGELOG.md file.

The compiler warns about &, and I think the author's intention
was && anyway.

This involves fixing the secondDerivativeOfDistanceSquaredWRTSecondArgument
method: Previously it returned a FieldMatrix, but the test requires
a SymmetricMatrix.

Add Simo-Fox shell model

See merge request !87

AlexanderMueller authored 3 years ago and Sander, Oliver committed 3 years ago

This commit adds the energy implementat for the nonlinear Reissner-Mindlin
shell model known as the Simo and Fox shell model.

Details may be found in

  "A consistent finite element formulation of the geometrically
   non-linear Reissner-Mindlin shell model [Müller, Bischoff]"

Correct the iterative calculation of the polar decomposition and its derivative

See merge request !59

Move the polar decomposition to a separate file and add the algorithm by Higham and Noferini (from Robin Fraenzel)

In the test for the Higham and Noferini algorithm, we see:
Unfortunately, for matrices that are close to an orthogonal matrix, this algorithm is
about 2x slower. One can benefit from the Higham and Noferini algorithm only if the
matrix is quite far away from an orthogonal one.

Before, the calculation was terminated after exactly three iterations, now the
stopping criterion is fulfilled if the change in the norm of the polar factor is
small enough.

Use correct vector type for the combination of displacement and rotation in...
