current_blogger :user # Preferably returns a User if one is signed in

current_bloggers # Currently signed in user and admin
current_blogger # Currently signed in user or admin
blogger_signed_in? # Checks whether there is either a user or an admin signed in
authenticate_blogger! # Redirects unless user or admin are signed in
