Added omniauth-google-oauth2 gem, a sessions controller, a user model, and some config files for omniauth.
Added omniauth-google-oauth2 gem, a sessions controller, a user model, and some config files for omniauth. For real I need to remember to add files before commit.
Not sure but we need the google.yml config file but it should be removed from git  but it's needed for heroku.
Hardcoded google as the provider in the callback route.
Google Oauth2 key and secret are now stored in ENV variables.
Oauth2 callback route was wrong now it is not.
Oauth2 callback route was even more wrong than previously thought.
Changed session#new controller to simply raise the auth info as some yaml just to check out what it provides.
Trying to set/create user from the auth callback
 Updated the view to show current user if logged in
user should be current_user in templates
Added a link_to Sign Out if signed in.
Changed route for Sign Out.
