Start an actor and register it in the

Any arguments passed to :meth:`start` will be passed on to the class
constructor.
Behind the scenes, the following is happening when you call
:meth:`start`:
1. The actor is created:
1. :attr:`actor_urn` is initialized with the assigned URN.
2. :attr:`actor_inbox` is initialized with a new actor inbox.
3. :attr:`actor_ref` is initialized with a :class:`pykka.ActorRef`
object for safely communicating with the actor.
4. At this point, your :meth:`__init__()` code can run.
2. The actor is registered in :class:`pykka.ActorRegistry`.
3. The actor receive loop is started by the actor's associated
thread/greenlet.
:returns: a :class:`ActorRef` which can be used to access the actor in
a safe manner
