Method which gets a chunk of HTML to perform standard Google Analytics tracking as well as a noscript version. Very useful for finding out what percentage of your users do not have JavaScript support.

This is Python port of the PHP example here: http://andrescholten.net/google-analytics-zonder-javascript/

To use, you need to put the following into your settings file:

GOOGLE_ANALYTICS_ID = 'UA-1234567-1' GOOGLE_ANALYTICS_DOMAIN = 'example.com'
