Nuemark plugins system (with mermaid as example)

[langhuihui]

mermaid in markdown is very useful to show graphs

Looks good. This makes a good example Nuemark plugin at least. Maybe even a tighter integration.

Mermaid support allows for creation of C4, and similarly important diagrams baked right into the markdown, meaning dev teams can literally document their inter system dependancies in the root readme, instead of being forced to have system documentation stored in different systems; a very bad form of tight coupling that is impossible to "know about" by opening just the repo.
