Resolve "Non-implemented functions lead to infinite loops in fluid system"

Closes #534

See merge request !1133

[staggered][fvElementGeometry] Inherit from cctpfa fvElementGeometry

See merge request !1146

[fluidsystems] remove isLiquid in favor of isGas

See merge request !1142

[staggered] add the scalar normal velocity to the Vtk output

See merge request !1149

This will facilitate reading from Vtk files.

[cleanup][freeflow] calculate molar flux to mass flux in case of useMoles false in fluxvariables instead of in ficks law. diffusion laws should always return the molar flux

* using cctpfa fvElementGeometry comes with a lot of difficulties,
  furthermore scvf(eIdx, localScvfIdx) is still needed

Cleanup/remove enthalpy and viscosity from constraintsolvers

Closes #519

See merge request !1136

[newtonsolver] Pass shared_ptr by copy

See merge request !1144

* won't compile otherwise

Also replace all calls to isLiquid by equivalent calls to isGas

[freeflow][rans] Set velocity gradient to zero, if it is a single element in on direction

See merge request !1130

[feature] test newtonconvergencewriter on 2pni test

See merge request !1139

[fluidstates] include necessary header in compositional.hh

See merge request !1138

[doc] Add preliminary contribution guide and style guide

See merge request !992

include valgrind and exceptions directly
as no method of the constraintsolvers is used.

move the calculation of enthalpy and viscosity to the volumevariables
and adapt the interphaces of the solve-methods
