    [stencil] Improve flux stencils · 7a7f10fa
    Timo Koch authored
    Fix the flux stencil for every method independent of the stencils used
    in the different flux laws. The matrix entries have to be reserved for all
    possible occuring stencils if the method has parameter or solution dependent
    stencils, otherwise the matrix needs to be rebuild every time. This implements
    this unified flux stencil for box, cc, ccmpfa.
    Remove a lot of duplicate code.
    Separate the physical laws from the dicretization stencil.
