/**
 * Includes Google Analytics tracking into the page.
 * 
 * Which google account is used for the tracking is probably
 * deployment-specific. This is therefore passed as a parameter to the
 * constructor of this object. It is advised that this parameter be set in the
 * web.xml file of the application, to allow it to be different on different
 * deployments.
 * 
 * If the account is null or empty, then the analytics tracking code is not
 * inserted into the page. (Perhaps some installations require the code, and
 * other installations do not.)
