A Covid detour

So we are catching up after both the 2021 year end and 2022 beginning were capsized by Covid. All the members of the team have been taken down with Covid at different points during the course of this work.  The double vaccinated compiler of this blog is still feeling the impacts more than a month after testing positive. So apologies for the break in transmission but Covid intervened. We will catch up with some retrospective postings to bring things up to date.
