Created a version 4 of make_formatted and generate_response to gather past and future trip options in a range of four days.  This will funnel into the dynamically changeable day buttons enabling a user to select a different day of a particular leg of a particular journey.  This will accomplish a more interactive UI.  Passing a large JSON string to a hidden input element for the JavaScript functions I am writing to handle and utilize for the accomplishment of this new dynamic system.
