Added jtmpl example

[jtmpl](http://jtmpl.com) is a micro library that enables the developer to focus on:

- write a Mustache template

- write a model for it, which can also include event handlers that manipulate properties

and assume generated DOM is synchronized with model at all times.

It infers bindings from template structure, no need to specify them explicitly. There is no learning curve, the best API is no API, you just have a single function.

It's still very young and used only in the KitchenSink demo and this TodoMVC implementation.
