which are associated with the equations that do not need initial
 residual compensation, to zero.

Adding a single space in incorrectly broken lines.

This avoids a warning at the end for unused vectors.

This simplifies the TimeDiscretization interface:
pushState and popState are no longer needed. The corresponding
copies are done in the time loop.
Since the previous time step solution is no longer stored
in the time discretization, it is passed to all required
functions like assemble, getRHS and the like.

This are all but backward Euler.
The few testcases in H2-pp were updated to backward Euler
without loss of accuracy.

 - All processes using a Newton scheme are discretized
for the backward Euler scheme only. They are not usable
with other time discretizations.
 - Greatly simplifies code maintenance in this part.

Include spdlog via BaseLib/Logging.h, which
provides macro replacements for
ERR/DBUG/WARN/INFO...

This causes the time step to fail and repeated if possible.

To access the solution values a dof tables are passed
too.

Foob = out-of-balance forces.

Pass process_id to FEM::assemble calls.

Fixes multiple copyright messages in the doxygen docu.

ag '\\file' -L --ignore=ThirdParty *Lib |xargs  sed -i 's/\(.*\)\\copyright/\1\\file\n\1\\copyright/'

It contains a boolean for met error norms and a
number of iterations of the solver made.

The number of iterations is needed for
a timestepping scheme.
