Feature/generalize 2pnc

* Adapt 2pnc to work with cell-centered too
* Add fuelcell cell-centered test
* Electrochemistry works without cubegridcreator
* Make more use of darcy flux variables
* Box test passed with old reference solution
* Adapt 2pncmin likewise

[el2p] Adjust name of friend class



See merge request !104

Analogous to ImplicitDarcyFluxVariables.

- Add a missing } in the test cc file.
- Add Dune::Geometries to CpFVElementGeometry.
- Fix the boundary transmissibilities.
- Change call to Opm parser routine to be compatible with Opm 2015.10.
- Adapt patches to Opm 2015.10.

* Changed test problem to work with both discretizations
* Added a cell-centered test problem with reference solution
* Use new gridcreator
* The box reference solution lost the boxVolume data array
* Make variable switch work for cc

* Remove boxVolume from output
* Generalize static data vector handling
* Generalize problem method initialPhase presence
* Introduce reactionlayer
* Add reference solution for the cc test

* Make current density publicly available
* Use standard grid creator
* Implement reaction source term for box and cell-centered

Feature/make fluxvars default constructible

Make all flux variables default constructable.

This merge request contains backward imcompatible. All flux variables
now have to be default constructed. Implementers of flux variables
need to make their implementation default construcable too.
All calls to the old non-default ctors will throw errors at runtime and
emit deprecation warning at compile time. FluxVars are no constructed
and update like this:

FluxVariables fluxVars;
fluxVars.update(...)

Being default contructable offers more flexible class inheritance
and more flexible caching possiblities.

* Simplifiy 2pnc and 2pncmin flux variables through inheritance
* Deprecates the unused `rhoFactor_` in 2p2c, 2pnc, and 3p3c
* [x] Fix 2pncmin test

See merge request !89

Clang warned about && and || without parenthesis which might
confuse readers

* Remove empty constructor
* Remove wrongly included config.h which is only needed in cc files
* Remove else after return in if branch

Cleaned up version is easier to understand

[richards] fix parallel test

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.

Introduce epsilon for floating point comparison in test.

This commit contains backward imcompatible. All flux variables
now have to be default constructed. Implementers of flux variables
need to make their implementation default construcable too.

Being default contructable offers more flexible class inheritance
and more flexible caching possiblities.

To this end especially the 2pnc/2pncmin flux variables where
updated to comform with other models. This involves some
deprecations. The 2pncmin reference had to be altered in the
velocity. The velocity was previously outputted wrongly as
the correct volumeFlux variable was never computed for 2pnc/2pncmin.

Feature/fs289 fluidframework doxygen

The Chapter fluid-framework is transferred to Doxygen.

- Explanations have been added to modules.txt 
- Function documentation for fluidstates, fluidsystems etc. transferred to header files. 
- Use of copydoc for general function doc.
- Rename handbook chapter Fluid-Framework to Material and Fluid Framework
- Replace content from Chapter in Handbook by reference to Doxygen module

Thanks to Martin Beck for contributing!

corrected the documentation for setFugacityCoefficient in the compositional fluidstate.

[sequential] replace decoupled by sequential

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.
