用法如下：
//设置Session
MyAppBase.SetSession("Username", "wahaha");
//如果设置的是一个实体类，则需要用JSON.stringify把实体转化为Json字符串保存
MyAppBase.SetSession("User", JSON.stringify(UserItem)); //获取Session
MyAppBase.GetSession("Username");
//用JSON.parse把Json字符串转化为实体
JSON.parse(MyAppBase.GetSession("User")); //跳转页面
MyAppBase.Navigate(bootPATH + "app/html/cctvlist.html"); //继承类
MyAppBase.Extend(ChildClass , ParentClass);
