Use of Google Analytics

This website uses Google Analytics, a web analysis service of Google. Google Analytics uses "cookies", which are text files placed on your computer, to help the website analyse how users use the site. The information generated by the cookie about your use of this website is usually transferred to a Google server in the United States and stored there.

You may refuse the use of cookies by selecting the appropriate settings on your browser. However, please note that if you do this you may not be able to use the full functionality of this website.
