/**
* 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 hierarchical
* 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 triangulation
* separately from the TriaLevel classes.
*
* This general template is only provided to enable a specialization
* below.
