/* Cookie controller for popup window
** Constraints: Cookie is set when popup fires, cookie contains timestamp for next cookie
**            : If this page is loaded before timestamp, popup doesn't fire
**            : Cookie value is set to "completed" when form is submitted, this stops any future popups

** This js file and dortch_cookies.js should be called on the page where the popup should appear
** and on the thankyou page for the form redirect
