(static) trackMedium()

Tracks the current utm_medium parameter. Alternatively attempts to extract the medium for the current session from document.referrer, if there is no utm_medium parameter. The outcome is stored in a session cookie. If there is no utm_medium parameter and the referrer is from the same domain, the medium stored in the cookie is not updated as this traffic is from within the same site. This function is intended to be called on every page of a site, allowing the traffic medium to be tracked on all entrypoints into the site.
