/**
ProgressIndicator subclass that listens to {@link LoaderEvent#onLoadProgress}.
@author Arthur Clemens
@version 12 Feb 2006
@use
Let the preloader indicator listen to Loader's 'progress' events:
<code>
loader.addEventListener(LoaderEvent.ON_PROGRESS, preloader);
</code>
Listen for the indicator 'finished' event:
<code>
preloader.addEventListener(ProgressIndicatorEvent.FINISHED,
EventDelegate.create(this, onPreloaderFinished));
</code>
In the 'handle finished' method, remove the indicator as listener:
<code>
private function onPreloaderFinished (inEvent:ProgressIndicatorEvent) : Void {
    var loader:Loader = movieManager.loader;
    loader.removeEventListener(LoaderEvent.ON_PROGRESS, preloader);
    // ...
}
</code>
