Can we and should we add an apply function in trait Message's companion
object which returns a `DefaultMessage`?
> Allow Message to be extensible

> Affects Versions: 0.8.3
> Reporter: Manu Zhang

>
> The current {{case class Message(msg: Any, timeInMillis: TimeStamp)}} is not
> extensible with an additional timestamp field while users' message may
> already carry that information. I don't think we care about what is stored
> in the message but what we can get from it.
> I propose to add a new interface {{Message}} with {{value}} and {{timestamp}}
> fields/methods and rename the current {{Message}} to {{DefaultMessage}} as a
> default implementation.
