Nice work! I have some requests on testing and documentation, and there are some style issues to fix (see inline).

Tests with compilation pass, the examples build and the user guide builds and displays nicely. The changes are covered. The branch also needs to be updated with the latest master.

[TeranIvy]

Almost there. There are some minor style and documentation changes to do.

Please also update the branch with the latest master if it changes before the next review round.

[TeranIvy]

All well now. Updated changelog and user guide for merge to master. If CI and Integration tests pass, this can go on.

[TeranIvy]

All well with the integration tests, proceeding to merge.
