Release notes / changes for 2.4.0
There should be a short document (e.g. CHANGES.md or so) mentioning the most important changes in dune-grid-glue 2.4.0, in particular those that require users to change their code.
Examples include:
- The changes to the extractor interface; new std::function interface.
- Deprecation of PSurfaceMerger
- Now requires C++11 and 2.3+ of the DUNE core modules. (At least I think 2.2 likely no longer works.)
- Support for range-based for with 2.4+ of the core modules.
