Re-thinking Big Bird.

I've pushed Big Bird from a controller / view into a single object named 'Module'. I've also rewritten the docs, commented the source and added a working carousel example.

All the tests have been rewritten into module.spec.js too.

Think this version makes MUCH more sense especially to differentiate us from BB and Ember et al. 

It's getting to the heart of what big bird is and we should always keep this in mind when developing it further.
