initial webapp

Here's a first version of the webapp (without any form of style).
It's written with Ember (using https://github.com/stefanpenner/ember-app-kit to scaffold a structure with building, testing and validating). 

I took most of the code from Globe and it looks like this right now:

__index:__
- the user can choose to get graphs from all fingerprints
- the user can choose to get graphs from a selected amount of fingerprints

Some open questions:
- where does the app gets participant fingerprints? Will there be an api?
- can the user change/insert fingerprints by himself?
- can it happen that the fingerprint request length is longer than the maximum url request length?
