CorrelationId (BlazingMQ Java SDK 0.0.10-SNAPSHOT API)

```
public interface CorrelationId
```
Provides an interface usable as an efficient identifier.
This is an interface, which can be used to identify any async operations. The CorrelationId internally provides an auto-assigned value (32-bit integer with 24 meaningful bits). It may also contain an optional user provided Object. PutMessage.setCorrelationId() can be used to consecutively generate a unique CorrelationId starting from 1 and up to 0xFFFFFF from multiple execution threads. Another flavour of the PutMessage#setCorrelationId can be used to generate similar unique CorrelationId that will held a user specified Object.
