Setting up the repo

A first proposal to set up the repository, following the latest from https://github.com/PK1A/hsp-hello-gulp
It is not optimal yet but it should cover most of what is needed to implement and publish these components.

I really find this syntax extremely not readable and ugly...

I would rather describe in our samples to use a real export outside of the statement
```
{template carousel using ctrl:CarouselController}
   <h1 class="carousel">Hello carousel</h1>
{/template}

exports.carousel = carousel;
```
