Create commentary (including flowchart) about constitution

[Ericson2314]

As the complex flowchart hopefully makes clear, I think the constitution is more complicated than it might first appear, especially after recent changes.

This commentary is supposed to make all this explicit.

Thanks, this felt kind of insightful.

I wondered if the states on half the seats being filled could be combined somehow.

Right, the charts looks correct to me. @wolfgangwalther you have usually a correct interpretation of constitution, wdyt?

As for this being the right place for this kind of content, I am not sure yet; I'll sleep on it and no better option emerges I'll approve.

I would like it to be in this repo at least, so future revisions to the constitution can modify the text and flow-chart in one step. But other than that, I have no preference.

This chart matches my understanding of what the constitution says regarding elections.

I'll defer to @7c6f434c, who certainly has a much better idea than I do.

Looking at this I can't help but think "this is too complicated - we need a simpler constitution"...

One thing that should probably be done: When the number of SC members falls below 4, no-confidence should be automatically triggered. Reduces the number of choices and also resolves #208 (comment).

@wolfgangwalther I agree it is too complicated.

But I think it is nice to merge the diagram before, so when we then make the simplification PR, we upgrade the diagram too, and the reviewers of the next PR can review the changes to the diagram and the changes to the constitution at the same time to make sure they match.

Conversely, if we make the diagram after we make the simplifications, we run the risk of voting on text whose meaning is not yet clear...because we don't have the diagram yet!

(I certain learned a lot about the constitution in making this diagram --- I simplify would not have been able to get it all straight without the diagram.)
