+Purpose: This is the software engine that runs the race car. It is a set of
+    commands that run from the beginning to the end and then start over each
+    time for as long as the car is turned on. This is called an 'infinite loop'.
+Parameters: None
+Returns: The main function always returns an 'int'.
