trait ActorStack extends Actor

Defines a trait supporting extending an Akka Actor's receive() via supreclasses and stackable traits without losing the extended behavior.
Defines a trait supporting extending an Akka Actor's receive() via supreclasses and stackable traits without losing the extended behavior. ActorStack implementations should wrap the r: Receive with their behavior, and call
```
case msg => super.around( r )( msg )
```
in order to not hide upstream stack behavior.
Concrete Actors must wrap all Receive expressions with around(...) in order to retain the stacked extension; e.g.,
```
case _: PostAdded => context become around( created )
```
ActorStack does not override any other Actor behavior.

package envelope

The enveloping package creates an envelope that carries a great deal more information than just the sender of the message.
The enveloping package creates an envelope that carries a great deal more information than just the sender of the message. The envelope contains the following:
- The class type of the sender
- The unique identifier of the sender
- The unique identifier of the intended recipient
- The class type of the message being sent
- The timestamp of the creation time of the message
- A unique identifier for the current “unit of work” in which this message is participating
- A sequence number that indicates where this message sits in the timeline of the unit of work
- A version number for the protocol version of the envelope
- The message itself
Importantly, all of this information to be supplied without burdening the code that sends the message. However, instead of the regular Akka tell and ! operations, programmers must use the send operation to wrap the message in a envelope.
```
someActor send SomeMessage( "Hello there, Mr. Actor" )
```
