remove the TargetSpace parameter of the Cosserat energy class -- Cosserat materials only make sense with RigidBodyMotion values

It will implement the energy of the elastic Cosserat modell
for continua and shells proposed by Patrizio Neff.  So far
it is only a copy of the harmonic energy, though.

using the ideas of Patrizio Neff.

In particular, this code should handle real 3d continua, as well

This initial commit only adds a lot of infrastructure.
