Previously, all triangulation classes of \texttt{deal.II} had in common that the coarse grid is replicated by
all processes in a parallel environment, and the actual mesh used for computations is constructed by repeated
-refinement. However, this has its limitations in industrial
-applications, where frequently the mesh comes
-from an external mesh generator in the form of a file that already contains millions

or tens of millions of cells. For such configurations, applications might exhaust
available memory already while reading the mesh on each MPI process.
