/*
* jquery-google-analytics plugin
*
* A jQuery plugin that makes it easier to implement Google Analytics tracking,
* including event and link tracking.
*
* Adds the following methods to jQuery:
*   - $.trackPage() - Adds Google Analytics tracking on the page from which
*     it's called.
*   - $.trackPageview() - Tracks a pageview using the given uri. Can be used for tracking Ajax requests: http://www.google.com/support/analytics/bin/answer.py?hl=en&answer=55519
*   - $.trackEvent() - Tracks an event using the given parameters.
*   - $('a').track() - Adds event tracking to element(s).
*   - $.timePageLoad() - Measures the time it takes  an event using the given parameters.
*
* Features:
*   - Improves page load time by loading Google Analytics code without blocking.
*   - Easy and extensible event and link tracking plugin for jQuery and Google Analytics
*   - Automatic internal/external link detection. Default behavior is to skip
*     tracking of internal links.
*   - Enforces that tracking event handler is added to an element only once.
*   - Configurable: custom event tracking, skip internal links, metadata
*     extraction using callbacks.
