照着todomvc官网的例子，做了一个avalon版的todos，功能全都有了，而且加了router模块，比司徒大大写的都完善(≧▽≦)/~
js文件整整100行，初次使用avalon，书写过程中绕了一些弯子，不过还好最终绕回来了。整体感觉如下：
- 相比用jQuery，代码量下去了，编码消耗的时间貌似更多了，一来是viewmodel需要一定的逻辑设计，不是像用jQuery那样一根筋一码到底，二来是可能我对框架还不是很熟，以后熟悉后效率会飞速提升。
- 有一些特性并不是想当然的那样，比如对数组监控，目前只能监控length的变化，数组元素如果是对象，属性发生变化无法监控。不过可以通过其他方式变通实现。
- view层能看到什么，vm层几乎都需要有一个属性与之对应，宁可多写一个属性，也不要绕别的逻辑来展示数据了。vm扁平化应该是设计思路。
demo展示如下：
