[WON'T FIX] Enhance integration tests (and wrapper factory etc) to generate PlantUML sequence transcripts for visualization.

per mailing list thread: http://markmail.org/message/ey5kgtx6xub7zyo5

The thread originally was motivated by the use case to forward-generate Java classes from a diagram, but also then got onto more general purpose round-tripping tools, plus the idea of generating diagrams from code, "after the fact"

Also mentioned in that thread is the idea of generating transcripts of tests for sequence diagrams; these would be as a side-effect of running integration tests. This ticket is for that idea.
