		MyMenu.AddItem(InnerHTML, Optional BackColor, Optional SubMenu);
		
	Extra functions:
		MyMenu.Display(Optional x, Optional y);
		MyMenu.Hide();
	At end of document HTML... 
		InitMenus();
	To create a main menu item/button
		WriteMainMenuButton(InnerItemHTML, MenuToShow, Optional NotSelectedBorderColor, Optional MyBorderWidth);
		
	Example:
		MyMenu=new Menu("#000000", "#00ff00", "#ffffff", 3, "#ff0000");
		MyMenu.AddItem("<a href=cnn.com>CNN</a>", "#ffff00");
		
		MySubMenu=new Menu();
		MySubMenu.AddItem("<a href=google.com>Google</a>");
		MySubMenu.AddItem("<a href=lycos.com>Lycos</a>");
		
		MyMenu.AddItem(Search Engines, , MySubMenu);
		
		WriteMainMenuButton("Links!", MyMenu);
Notes:
	Do NOT nest MenuA in MenuB in MenuA (recursion)
	Do NOT nest MenuB twice in MenuA
