Using node-static npm package for serving examples - python dependency eliminated, hooray!

Hi,
Will not it be better to use nodejs for serving examples? And have no python dependency?

__What I did?__

* Updated existing dependencies
* Added node-static dependency
* Added simple script for serving examples

__How to use it?__

```
npm install
node examples.js
```
