Add examples folder

Rebased on pr #18 

The React example works well :) And illustrates the minimal code required for daybed.js integration

* [x] **React** : TODO
* [x] **jQuery**: fullcalendar
* [x] **Leaflet**: meteor-leaflet demo clone
* [x] **Angular**: wishlist app
* [x] **[wingspan](https://github.com/wingspan/wingspan-forms)** : Form validation and errors
* [ ] ~~Ember~~ gave up
* [ ] ~~Offline first~~ daybed.js not ready


Ideas : 

* Wiki (client-side markdown rendering, each page is a record, everyone read_all )
* ~~Wishlist (each wishlist is one record with field type list of objects)~~ c.f Angular
* Comments system (à la disqus)
* Quotes
* Draw on a wall (à la http://leplatrem.github.io/Leaflet.gribouille/)
