1. Mastering Functions

A function is a mapping from one set, called a domain, to another set, called the codomain. A function associates every element in the domain with exactly one element in the codomain. In Scala, both domain and codomain are types.

val square : Int => Int = x => x * x

The code below is not intended to be a general purpose approach, but rather a 
simple CmdHandler / EventHandler model prototype that illustrates a concept of 
how to share an Eventsourced Processor stream among many child actors of 
same type. 

Snapshotting is important for children in order to get quick start up and avoid
filtering too many sibling events.
