This is a MVP .NET Actor Model toolkit that follows the
Akka API as closely as possible, but as idomatic C#. It
is licensed under Apache 2.0.

What's In a Name?
-----------------
Dotsero, Colorado: http://en.wikipedia.org/wiki/Dotsero

Currently supported:
--------------------
1. ActorSystem
   - /user
   - /sys
   - /sys/deadLetters
2. Actor, Props, ActorContext, and ActorRef
   - Any number of typed OnReceive() methods
   - Stack-based Become/Unbecome
3. ActorPath (very lightweight)
4. ActorSelection (currently no wildcards)
5. SupervisorStrategy
   - OneForOneStrategy
   - AllForOneStrategy (not fully implemented)
6. System Scheduler (timers)

- Requires Retlang: https://code.google.com/p/retlang/
- Currently seeing approximately 0.5 million messages per second,
  with only two threads, on a Intel i7 Quad Core 4700HQ 2.4 GHz.
- See unit tests for usage.

Currently unsupported (big items missing):
------------------------------------------
1. Configuration
2. EventBus/EventStream
3. Remoting and Clustering (LocalActorRef/RemoteActorRef)
4. Creating and stopping actors is currently not asyncrhonous,
   and the ActorKilledException/Stop messages are currently
   not supported. Further, if a message is delivered to a
   suspended actor (e.g. due to a restart) the delivery
   currently blocks rather than stashing messages. This is
   because stashing would require another incoming message
   to cause the stashed messages to be delivered. A scheduler
   would be the thing to cause the stash to be emptied. The
   good news is that the block is a sleep and will likely
   last only one 1 ms interval.
5. Death Watch
6. Whatever else is not listed above as supported.
