mass Framework前后通吃，后端是基于node.js组建起来。后端与前端不一样，是依赖于node.js内置模块提供的一些API，因此前端那些依赖于浏览器提供的DOM API的模块无法复用。现在掐指一算，基本上核心模块上只有lang, flow能用得上，more则多一点，如random, pinyin, base64, uuid...

node.js内置了模块加载机制，这与我在前端使用的API非常不一致，我就再把它包装一层。核心模块与前端的核心模块在其他方法也尽量保持一致，当然像domReady在后端就不需要，去掉。如类型判定，由于是V8引擎，支持ECMA262v5，因此可以写得精简。最大的不同是，DEBUG用到mass.log，它的第二个参数是表示格式化高亮。

代码是暂时丢在这里，以后还要做各种扩展的！
