/**
* Effect is a wrapper for the Scriptaculous effects JavaScript library,
* which can be found at http://script.aculo.us/.
*
* Example of using an effect with options:
*
* <pre>
* Effect.highlight(widget, new EffectOption[]{
* new EffectOption("startcolor", "#ff0000")
* });
* </pre>
*
* Example of using an effect with no options:
*
* <pre>
* Effect.fade(widget);
* </pre>
*
* Example of using an effect on a specific element id:
*
* <pre>
* Effect.switchOff(RootPanel.get("leftNav"));
* </pre>
*
* You must reference the Scriptaculous JavaScript code in your HTML
* page to be able to use the wrapper. Failure to do so will result in
* error messages similar to this, ""$wnd.Effect.Fade" is null or not an object".
*
* <pre>
* <script type="text/javascript" src="script/prototype.js"></script>
* <script type="text/javascript" src="script/scriptaculous.js"></script>
* </pre>
*
* You will also need to add the gwt-widgets jar file to your project classpath,
* and add the following reference in your .gwt.xml file:
*
* <pre>
* <inherits name="org.hanson.gwt.widgets.WidgetLibrary"/>
* </pre>
