Start ? You should get it at network generation time (i.e. without 
running anything)

That's definitely the case.

Slave activities should inherit the triggers from their triggering 
component.

The two methods that will need to be modified (on the same class) are
   #initial_information(task) => should not call #done_task_info (at the 
end of the method) if the activity is a slave activity
   #done_task_info => set the task information from the task to its 
slaves (using #add_task_info) and call #done_task_info on them.
