RodSolver is now called RiemannianTrustRegionSolver, and can be parametrized with the TargetSpace.  Some remains of RigidBodyMotion are still there, though.

now works on a per-element basis and has been moved to the local rod assembler.
That way, it has lost most of its 1d-ness.  In the future, it will be usable
for other problems as well.

The class 'Configuration' is now called 'RigidBodyMotion', and can be parametrized by the space dimension
