+NOTE: THIS FILE IS EXCLUDED FROM OUR UNIT TESTS.
+STARTING A WSGI SERVER IN A CI IS A BIT SKETCHY AS IT
+MAKES ASSUMPTIONS ABOUT THE STATE OF THE HOST SYSTEM.
+
+FOR EXAMPLE, PORT CLASHES COULD CAUSE THE TEST TO FAIL
+DESPITE THE CODE ITSELF BEING TOTALLY FINE.
+
+THIS DOES MEAN THAT EXTRA CARE SHOULD BE TAKEN WHEN
+DEVELOPING THIS SECTION OF THE CODE.
+
+THANKS
