Prototype Archi export

[davidwatkins73]

Investigate Archi as a possible integration point with Waltz. Current thoughts are to select an Application Group in Waltz and export:

• [x] apps
• [ ] servers
• [x] logical flows
• [ ] databases
• [ ] (selected) taxonomy relns

Issues:

• no obvious way to merge models, i.e. it will be tricky to refresh an existing model file with new entries and preserve modifications
• folder structures are lost during import (export shows them but import seems to ignore them)
  • associated issue

Looks like the folder structure issue has been fixed in Archi. Bumping this up to give it another try.
