Starting to play with a slightly different UI for structured conversations

Migrating to a new platform based on Scala, I am testing some new ideas on conversation tree navigation. The test site is here. The source code for it is here.

Scala is a language that compiles to Java byte codes; it is built for parallel computation, actors, and other features that make it valuable when the game is scalability.

The navigation experiment is that of a column browser, not unlike the finder in Macintosh. The code is still under rapid evolution, but close to settling down.
