/**
*
* <h4>DoFFaces</h4>
*
* These classes are similar to the DoFLevel classes. We here store information
* that is associated with faces, rather than cells, as this information is independent of
* the hierarchical structure of cells, which are organized in levels. In 2D we store
* information on degrees of freedom located on lines whereas in 3D we store information on
* degrees of freedom located on quads and lines. In 1D we do nothing, as the faces of
* lines are vertices which are treated separately.
*
* Apart from the DoFObjects object containing the data to store (degree of freedom
* indices) we do not store any data or provide any functionality. However, we do implement
* a function to determine an estimate of the memory consumption of the contained
* DoFObjects object(s).
*
* The data contained isn't usually directly accessed. Rather, except for some access from
* the DoFHandler class, access is usually through the DoFAccessor::set_dof_index() and
* DoFAccessor::dof_index() functions or similar functions of derived classes that in turn
* access the member variables using the DoFHandler::get_dof_index() and corresponding
* setter functions. Knowledge of the actual data format is therefore encapsulated to the
* present hierarchy of classes as well as the dealii::DoFHandler class.
