Akka actor benchmark

Scala (Akka) actor performance test aka benchmark.

Program should be run with three arguments:

1. actor count (A)
2. message count (M)
3. message processing time in milliseconds (T)

If actor count == 1, then the script sends all M messages to that actor. If count > 1, then the script randomly sends M messages to A actors. Each message is processed by corresponding actor for T milliseconds.

Use SBT for automatically downloading Akka and running program.
