  SxMapEnumerator
  
  This enumerator goes over all objects in the source enumerator and
  calls the mapper callback on each to perform some operation on them.
  
  The callback method needs to have a format like:
  
    - (id)mapObject:(id)_object;
  
  note that it will be passed the "nil" object to terminate the events.
