 * Shows how agents exchange messages by targeting roles.
 * Receiving a message, you can learn information about the sender. This is illustrated firstly in this example.
 * Sometimes, agents need to communicate by replying to messages. There are primitives for that and they have two
 * advantages. (1) This will identify the message as being a concrete reply to the received message thus easing the
 * programming of protocols for instance. (2) This greatly improves code legibility
