* Java Toaster is a java utility class for your swing applications

* with a notification message and/or an associated image
* (like msn online/offline notifications).
*
* Toaster panel in windows system follow the taskbar; So if
* the taskbar is into the bottom the panel coming from the bottom
* and if the taskbar is on the top then the panel coming from the top.
*
* This is a simple example of utilization:
*
* import com.nitido.utils.toaster.*;
* import javax.swing.*;
*
* public class ToasterTest
* {
*
* public static void main(String[] args)
* {
* // Initialize toaster manager...
* Toaster toasterManager = new Toaster();
*
* // Show a simple toaster
* toasterManager.showToaster( new ImageIcon( "mylogo.gif" ), "A simple toaster with an image" );
* }
