Structure for storing degree of freedom information for cells, organized by levels.
Note that vertices use a storage scheme that is entirely separate from the one used for the cells. The indices of degrees of freedom located on vertices are therefore not stored here, but rather in member variables of the DoFHandler class.
The indices of degrees of freedom located on lower dimensional objects, i.e. on lines for 2d and on quads and lines for 3d are treated similarly than that on cells. However, these geometrical objects, which are called faces as a generalization, are not organised in a hierarchical structure of levels. Therefore, the degrees of freedom located on these objects are stored in separate classes, namely the DoFFaces
classes.
Access to this object 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 DoFHandler class.

std::vector<types::global_dof_index> internal::DoFHandlerImplementation::DoFLevel< dim >::cell_dof_indices_cache 
Cache for the DoF indices on cells. The size of this array equals the number of cells on a given level times selected_fe.n_dofs_per_cell().
