Message class defines a transient notification including a namespace, a name, and a valid payload.
Messages are not retained or stored after all their listeners have been processed, so messages should only be used for communicating information that never needs to be persisted or recalled.

Constructor.
The constructor builds a Message object containing a namespace, name, and payload
to deliver to other tiles using their event listeners.
ns:String — The namespace of the message.
| |
name:String — The name of the message.
| |
payload:* — Any object that is allowed to be serialized. The object will be sent to every listener.

Clones this Message instance. Duplicates an instance of an Event subclass.
Returns a new Event object that is a copy of the original instance of the Event object.
You do not normally call clone(); the EventDispatcher class calls it automatically
when you redispatch an event—that is, when you call dispatchEvent(event) from a handler
that is handling event.
The new Event object includes all the properties of the original.
When creating your own custom Event class, you must override the
inherited Event.clone() method in order for it to duplicate the
properties of your custom class. If you do not set all the properties that you add
in your event subclass, those properties will not have the correct values when listeners
handle the redispatched event.
In this example, PingEvent is a subclass of Event
and therefore implements its own version of clone().
class PingEvent extends Event {
var URL:String;
public override function clone():Event {
return new PingEvent(type, bubbles, cancelable, URL);
}
}
Event — cloned Message
