* 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

Introduce epsilon for floating point comparison in test.

See FS#250 for details.

- The required binary coefficients are added.
- Electrochemistry equations added for both isothermal and non-isothermal cases (Non-isothermal are not used till now).
- pc-s relation for hydrophobic material  added
- h2ON2o2 fluid system added
- fuelcell test case is the new test problem for 2pnc model.

Moreover, some updated related to 2pncmin model are included

Reference solution for 2pncmin test is changed (Now solution for the last timestep and is used for comparison). 
The similation endtime is also reduced.

- Units in the fluidsystem/brinevariablesalinity and components/nacl checked. Additional commented units removed.
- Commented cout statements removed from computefromfugacities2pncmin, computefromreferencephase2pnc and miscible2pnccomposition
- The ccommented out removed from problem file and input file corrected.
- The test case is checked for both debug and optim model with clang compiler.

New test case for 2pncmin model added to dumux/test. For this following additional files are needed (Reviewde by Johannes)

- For variation of salinity in brine the needed constitutive relations are implemented in components brine_VerSalinity.hh and nacl.hh
- Additional constraint solvers (compositionfromfugacities2pncmin and computefromreferencephase2pncmin) are needed, specially for the case nPhaseOnly
- Additional constraint solvers (computefromreferencephase2pnc and miscible2pnccomposition) are needed for 2pnc cases in general.
- Fluidsystem brineairfluidsystem is updated
- Binerycoefficient file for brine_air case is included. 

- A test case for 2pncmin model is included for flusiong of precipitated salt in gas reserviors. The includes corresponding problem file, spatial parameters file, input file and *.cc file.
- For this the CMakeLists.txt is also updated.
- A reference solution 2pncmin test case "injectionbox2pncmin-reference" is included to test/references folder
