<descr>
<p>
<var>Notification</var> is an overridden method used to perform actions needed
when a component is added to or removed from the class instance. It calls the
inherited method on entry to remove the free notification for the component
and to signal the Notification method for any child components. In TScreen, it
ensures that an internal member used to track the value in ActiveControl or
ActiveCustomForm is <b>Nil</b>'d when AComponent is removed and it is stored
in one of the members.
