I have business objects tree which i receive from from datasource.
Each element of tree is node<T> where T is business object type, on the
same level of tree T-types are same.
Then i traverse the tree for warm up/build actor system, pass to actor
constructor business object T and list of children - List<Node<U>> for
creating child actors.
Its like cascade initialization.
When the *Actor *received *msg *:
1. it modify *Actor *business object state
2. depends on object state, *Actor* sends msg to *CommanderActor* wich call
business command.
3. then *Actor* have to route msg to one concrete child actor.
4. Then the same steps from *1* to *3* are executed for child actor and so
one.
