regularjs todomvc example

This is an implementation of TodoMVC for [Regularjs](http://regularjs.github.io/) framework.

Regularjs is a flexible framework used for creating data-driven component. It has string-based template with modern syntax, and it provides directive, filter, animation and other important features. In addition, in regularjs, every component is well encapsulated and can be easily extended from other components using builtin [kclass](https://github.com/ded/klass).
Compared to angular, regularjs is much more smaller. It mainly focus on the UI data-driven layer, and it uses string-based template instead of dom-based template, so we can control our template more preciously, and because of the parsing phase of regularjs, we just see clean dom in the end, without the binding information shown in the node. Besides, computed property are supported, so we can handle complex data binding relationship.
