make a new subdirectory 'coupling' for coupling stuff and move the new file rodcontinuumcomplex.hh there

This class should centralize some of the logistics needed for the knee
models and similar stuff.  Eventually, domain decomposition solvers should
be able to work on this data structure.  That is still a way off, though.

add a dummy method derivativeOfDistanceSquaredWRTSecondArgument.  Only throws an exception.  The implementation will follow later

This is a snapshot commit.  It compiles, but I haven't actually dared
to run it yet.

Kinda stupid... but the new implementation is shorter, and it is merged into the old
method.

It was a RigidBodyMotion before, but the rotation part of that was
ignored.  Semantically it is just a position, hence a FieldVector
is better.

Only Dirichlet-Neumann is complete and appears to work, but it is
not really tested yet.

These are needed for general Steklov-Poincare methods.

set IPOpt print_level to 0 if Solver::QUIET is requested.  Negative values appear not to be allowed anymore

transpose one gradient matrix.  This makes the code run, but it still doesn't work even for RealTuple<1>
