Detailed Description

Temporarily disables a Notifier.

Notifiers can be disabled. To do that temporarily, use NotifyStopper. If the Stopper goes out of scope, the callback is re-enabled. like:

void xxx:doSomething()
{
    NotifyStopper stopper( a_notifier );
    // Doing things that would otherwise trigger Notifier.
    // On exit, Notifier gets re-enabled automatically.
}

To stop notifications only to a certain object (usually 'this'), pass the object as 2nd argument to the constructor.
