Commit 219dd9 defaulted the linear solver to a sequential one. Since
the box Richards test is running in parallel, a parallel linear
solver has to be set. The AMGBackend gives slightly different results
above the fuzzy threshold. Therefore, also the reference solution is
adapted.

Replace the word "Decoupled" in TypeTags and classes by "Sequential",
according to FS#252.

For both the TypeTags and the Decoupled...Indices classes, the compilers
don't emit a deprecation warning. For the TypeTags, a run-time check is
performed at the end of the start() routine.

* Test now reaches the inhomogeneities.
* Introduced epsiodes to reduce vtu output
* Increase end time

Ignore the porosity for all box models since it is defined element-wise
in these test but the default 2p2c implementation outputs porosity per
vertex. Depending on the order of the elements, the porosity would
differ in these cases.

A base problem on the model level was necessary

Timo Koch authored 9 years ago and Christoph Grüninger committed 9 years ago

Using correct floating point comparison with epsilons led
to a alightly different solution. Reference updated.

Use input gridcreator instead of structured dgf file

Get rid of external grid managers
Use coarser mesh (65x65 instead of 85x85)

Argument dependent lookup deduces the Dune namespace from
the function arguments that are also in namespace Dune.

only the ni-base-model will be listed in the module list
ni-test-problems include docu from non-ni-base problem

Implement a temperature() function in the volvars and use it
instead of volvars.fluidstate().xtemperature().
This reuqired the implementation of two template functions
to ensure that the correct temperature() function is called
depending on the number of energy equations considered.

Use volVars.moleFraction(wPhaseIdx, NaClIdx) instead
of volVars.fluidState().moleFraction(wPhaseIdx, NaClIdx)

Implement a pressure()  and density() function in the volvars and use it
instead of volvars.fluidstate().x(phaseIdx).

After commit 8557b77e
which fixed shadowed variables in the fluidsystem,
the test did not pass anymore. In addition, a new grid
creator is used now which also leads to slight differences in the
coordinates. Therefore, the reference solution had to be updated.

Fixes a bug with conditional jump over uninitialized values, which was intoduced by generalizing how massFractions are set.
This keeps the generalization, but reverts everything else to what it has been before.
Changes in reference solutions are necessary due to small changes.

Thanks gruenich for git-bisecting.

This changes the reference solutions.

This requires updating the reference solutions.
For mpnckinetic it was not able to check, whether the reference solution was already broken before.
