    CoolWindow 程序
    
    创建者:张云飞
    
    使用方法:
    
    
    1.创建窗口
    var aWin = new CoolWin("ID", "宽", "高", "左", "顶", "标题", "窗口内容");
    
    var exWin = new CoolWin("id1", "250", "200", "100", "100", "示例", "COOLWindow示例");
    
    
    2.显示窗口
    
    ShowWindow("id1", null);
    
    3.隐藏窗口
    
    ShowWindow("id1", "none");
    
    3.关闭窗口
    DestroyWindow("id1");
