* use small indicies for loops
* do not query for dofs using < 0 to check if they exist
* remove superfluous this-> calls
* use efficient types, clean up loops
* move axis and pair data to namespace Detail

* suppress compiler warning

[fluxvariables][gridfluxvarscache] adapt the fluxvariables to check for higherorder via the gridfluxvarscache, not the problem

[higherorder] expand the geometry, stecil, and flux calculations to include higher order flux limiter methods

* treat fluxes over boundaries properly (Neumann fluxes
  were not considered before)

* simplify volume flux calculation: just use v * A

* 2 Latex-errors and 2 ingroup-errors left

* if a couplingContext is not yet correctly bound, it now can just
  do that itself
* change the signature of some methods to have the element at hand

* allow setting a fixed value anywhere in the domain
* do not use boundaryType but a separate function to check for fixed cell
* set 1.0 on the diagonal in the system matrix and 0.0 for the off-diagonal entries
  to improve numerical accuracy

* move to RANS problem

* remove property

* add source (gravity) term to residual, also when face has Neumann BCs
* correct coupling condition

* use bind instead of bindElement

[freeflow][outflow BC] Introduce that there is no gradient normal to the outflow boundary in cases where the outflow boundary is the normal face with respect to the assembled scvf.

[freeflow] Move calculation of BJS-velocity to model and adapt the calculation of velocity gradients for the RANS models
