/**
 * This class is responsible for adding actions to scheduler, and to build and sent perceptions.
 *
 * <p>The goal of the RP Manager is to handle the RP of the game. This means:
 *
 * <ul>
 *   <li>run RPActions from clients
 *   <li>manage RPWorld
 *   <li>control triggers for events
 *   <li>control AI
 * </ul>
 *
 * <p>This is a HUGE task that is very complex.<br>
 * Hence we split that behaviour in different class:
 *
 * <ul>
 *   <li>IRuleProcessor will handle al the RP logic and run actions from client. This class will
 *       also implement AI, triggers, events, rules, etc...
 *   <li>RPWorld will handle all the world storage and management logic.
 * </ul>
