UML diagrams in documentation

[marcus-oscarsson]

Adding the possibility to add UML diagrams via for instance plantuml, what do you think is it practical or is there a better way of doing it ?

Yes, we had discussed this already here: #889 (comment)

I can have a closer look at this in the next days and come up with a concrete proposal (a pull request).

Let's close this in favor of this other older ticket: #908
