Documentation
Documentation has been written, but is not yet complete. It's currently available in the AttSearchEngine.root file, in the outline at AttSearchEngine.["#Documentation"]. There are enough docs there now for any developer to start using AttSearchEngine immediately. It includes fully-functional examples.
Docs will also be posted here.
As more docs are written, they'll be available here on this page, and to all users via the root-updates process.
