   Ownership of events etc. is handled by the following policy: As soon as an
   event (or any other subclass of IncidenceBase) object is added to the
   Calendar by addEvent() it is owned by the Calendar object. The Calendar takes
   care of deleting it. All Events returned by the query functions are returned
   as pointers, that means all changes to the returned events are immediately
   visible in the Calendar. You shouldn't delete any Event object you get from
   Calendar.
