/* *************************************** 
 *            NiceMenu.cs
 *  --------------------------------------
 *  This is an improvement by Francesco Natali ([e-mail])
 *  over an improvement by Sajith M 
 *  of the "Visual Studio .NET Menu Style" 
 *  by Carlos H. Perez that appeared on CodeProject 
 *  (http://www.codeproject.com)
 * ---------------------------------------
 *		     How to use it
 *  You have to add: 
 *		using Utility.NiceMenu;
 *  and after the "InitializeComponent()" code:
 * 		NiceMenu myNiceMenu = new NiceMenu();
 *		myNiceMenu.UpdateMenu(this.nameofyourmainmenu, new NiceMenuClickEvent(nameofyourclickfunction));
 * ---------------------------------------
 *  With only three lines of code your menu
 *    will be AUTOMATICALLY updated with 
 *       a new great .Net style menu!
