Word Processor Challenge

This was a little task I was assigned for an interview, after completing I had some ideas to expand and deploy it for fun.

I started by expanding out from a single Agent to a DynamicSupervisor with a process Registry for tracking dynamic Agents acting as "Rooms". I then added "Personas" for an anonymous user system to incorporate Presence tracking. Finally I moved the event system over from ephemeral PubSub state to ETS, this allowed the incorporation of long-term events that can also be reverted.
