Subscription (mbassador 1.2.0 API)

```
public class Subscription
extends Object
```
A subscription is a thread-safe container that manages exactly one message handler of all registered message listeners of the same class, i.e. all subscribed instances (exlcuding subclasses) of a SingleMessageHandler.class will be referenced in the subscription created for SingleMessageHandler.class. There will be as many unique subscription objects per message listener class as there are message handlers defined in the message listeners class hierarchy. The subscription provides functionality for message publication by means of delegation to the respective message dispatcher.
