Moved comments block and commented out user sign up form on question#show page
Added model spec for answer. Created basic logic on questions#show to conditionally reformat answer form. Refers to #22 and #45
Actually added spec for new model
Answer is being saved properly
rendering answer on question page when present, hiding answer form when one answer present, added has_many :answers to question model
removed answered boolean from question and added answered? lookup method
Added an image to the :person_ny_sheldon_silver factory so that the cdn_image_tag application helper function would not fall over when running specs. Added spec checking if the answered property of a question that is answered returns true. Added specs to check whether the page renders properly when a user who is verified as a responder visits a question page where they can respond.
Added nil check on for url on cdn_image_tag application helper so we don't have to define an image in the :person_ny_sheldon_silver factory
Changed 'or' to '||'. Added back the form to register and sign on. Added a button for non-signed-in users to sign up as a responder
removed 'not' operator and changed answer sign up button to a link on questions#show
