/**
 * This class let's you register every navigation event to a Google Analytics
 * account. To use it, you must bind GoogleAnalytics as eager singleton in your
 * gin module and also bind the annotation {@link GaAccount} to your Google
 * Analytics account number:
 * 
 * bind(GoogleAnalyticsImpl.class).to(GoogleAnalytics.class).asEagerSingleton();
 * bindConstant().annotatedWith(GaAccount.class).to("UA-12345678-1");
 * 
 * If you want to log custom events, see {@link GoogleAnalytics}.
 *
 * @deprecated Since 1.4. Use https://github.com/ArcBees/universal-analytics instead.
