* Enables cross domain linking. By default, the visitor ID that identifies a unique visitor is stored in
* the browser's first party cookies. This means the cookie can only be accessed by pages on the same domain.
* If you own multiple domains and would like to track all the actions and pageviews of a specific visitor
* into the same visit, you may enable cross domain linking. Whenever a user clicks on a link it will append
* a URL parameter pk_vid to the clicked URL which consists of these parts: 16 char visitorId, a 10 character
* current timestamp and the last 6 characters are an id based on the userAgent to identify the users device).
* This way the current visitorId is forwarded to the page of the different domain.
*
* On the different domain, the Piwik tracker will recognize the set visitorId from the URL parameter and
* reuse this parameter if the page was loaded within 45 seconds. If cross domain linking was not enabled,
* it would create a new visit on that page because we wouldn't be able to access the previously created
* cookie. By enabling cross domain linking you can track several different domains into one website and
* won't lose for example the original referrer.
*
* To make cross domain linking work you need to set which domains should be considered as your domains by
* calling the method "setDomains()" first. We will add the URL parameter to links that go to a
* different domain but only if the domain was previously set with "setDomains()" to make sure not to append
* the URL parameters when a link actually goes to a third-party URL.
