Mapping

- µCtrl's model update
- Model can emit events on save and destroy
- Mapping from and to NinjaBlock
- Crawler (fetchAll and pushAll)
- Some tests have been done.
- Need to create tests files with Mocha...
- Steps to fetch all the data : 
- Create an user with the userAccessToken (POST : http://localhost:3000/users). It will retrieve all your infos and give you an µCtrl token.
- Fetch all the data : (GET : http://localhost:3000/users/:µCtrl_Token)
@jpgauthier , @bobbylavoie ... There's something I'm missing here.  We'll take this offline, just taking notes:
* POST /users = create.  This code is more like ninja.getUserID.. :question:
