Create Questions and Answers

OK So, the question and answer buttons work dynamically and the input fields are numbered. 
Everything works and nothing is broken! Yay! 

WARNING there is a fake route in the controller that is linked to in our form. It can be deleted because it's not for anything. It looks like this: "post '/surveys/questions/new' do params end" 

TO DO NEXT format the answers so that they are nested underneath their question, so it's easy for the user to see which answers go with which questions.
