Enable rotational-symmetric geometries for the staggered/freeflow models
- Add classes for face-related frontal/lateral scvfs and scvs so they can be modified through the traits
- Make makeBoundaryFace a free function. This allows the scvf to be wrapped (as necessary for rotational-symmetric geometries)
- Add rotational-symmetric stationary stokes pipe flow problem
