The main thing this does is to split the comparison tests between sequence and block configuration into three tests each to allow the block and sequence jobs in parallel and then run the comparison subsequently. With this working I went ahead and then used the same test structure in AnalysisBase as well.
This also required some minor fixes, as well as putting in some tests in a disabled state, because logically they ought to exist, but they are not working and were not present/disabled up to now.
