Function documentation

void Activate()

 Activate a system event handler. All handlers are by default
 activated. Use this method to activate a de-activated handler.

void DeActivate()

 De-activate a system event handler. Use this method to temporarily
 disable an event handler to avoid it from being recursively called.
 Use DeActivate() / Activate() instead of Remove() / Add() for this
 purpose, since the Add() will add the handler back to the end of
 the list of handlers and cause it to be called again for the same,
 already handled, event.
