* General template for information belonging to the faces of a triangulation. These classes
* are similar to the TriaLevel classes. As cells are organised in a hierarchical
* structure of levels, each triangulation consists of several such TriaLevels. However the
* faces of a triangulation, lower dimensional objects like lines in 2D or lines and quads
* in 3D, do not have to be based on such a hierachical structure. In fact we have to
* organise them in only one object if we want to enable anisotropic refinement. Therefore
* the TriaFaces classes store the information belonging to the faces of a
* triangualtion seperately from the TriaLevel classes.
*
* This general template is only provided to enable a specialisation below.
