      public HookMessage(HookMessage.AgentActionEvent hookType)
      This message should be used to request or release a hook on an agent action. The message should be sent to the kernel (which is the manager of the SYSTEM group in the local community), here is an example : 
       
 sendMessage(
        LocalCommunity.NAME,
        LocalCommunity.Groups.SYSTEM, 
        Organization.GROUP_MANAGER_ROLE,
        new HookMessage(AgentActionEvent.REQUEST_ROLE));
      In this example, the sender will be informed by the kernel of all successful requestRole operation made by the agents. This information will be transmitted using a subclass of HookMessage depending on the nature of the event. That is, OrganizationEvent, MessageEvent or AgentLifeEvent messages will be sent by the kernel according to the type of the hook which has been requested.

      To give up the hook, just send to the kernel another message built with the same action and it will remove the sender from the subscriber list.

      Parameters:
      hookType - the action event type to monitor
