Run auth_fitbit.py to get credentials for read access to a user's data,
$ python auth_fitbit.py [FITBIT CLIENT KEY] [FITBIT CLIENT SECRET]
This scripts open a browser window where you can log in to your Fitbit account and authorize the app to "access your profile and data". When you accept, the site will give you a string to copy and paste back into the script, which then writes the credentials to a local file named fitbit.yaml.
