//------------------------------------------------------------------------------------用户桌面和程序数据初始化区域----------------------------------------------------------------------------------------------------------------
Namespace.register("U.MD.D"); //桌面onload和桌面总控的命名空间
/*
window.onload的流程：
1、自由属性的设置，例如：页面识别id。允许浏览器多页面浏览www.1473.cn
2、加载各种事件绑定，如：页面大小监视，不允许选择桌面文字，ie7以下浏览器页面提示
3、加载桌面图标。
4、加载跨域设置，如果没有跨域，首页数据无法获取
4、加载首页
5、加载广告，QQ登录等外链。

UD和UC区别 uc是框架函数 ud为操作系统原壳 这里的简化的目标很简单 只要有人应用ud 就会引用一个web操作系统 提供操作系统的功能应用
难题 :
1、命名和用户冲突 会导致原web系统不可使用
2、函数冲突 如 用户自带window.resize这样的函数 我们提供了接口 但是这个接口的的暴露性可见性体现出文档的重要 宣传文档也就是文宣的重要性高了
3、有参数注释的都为暴露接口类型 其他都为内部使用 更好的体现方式
