Support groups in sequence diagrams

[ludwhe]

Description

Mermaid and PlantUML support grouping participants in boxes, which could help sequence diagrams exported from Structurizr act more like its collaboration diagrams (i.e. show software system and group boundaries).

This would basically mean grouping participants according to the model when generating sequence diagrams. PlantUML supports nested groups, while Mermaid seems not to: this could imply choosing a relevant default group for Mermaid depending on the view definition scope.

Priority

Low (I'm willing to make a pull request - please confirm approach first)
