Doxygen documentation title (?.?.?)
In the Doxygen documentation tittles appear (?.?.?). See for example this page https://www.dune-project.org/doxygen/pdelab/releases2.4/. I suppose that there should be displayed the module version.
The doxygen flags are set in the same way in the core and in the other discretization modules but for some reason only the cores are displayed correctly.
