* <ul>
* <li>the dynamically generated list of all API methods via "getReportMetadata"</li>
* <li>the list of metrics that will be returned by each method, along with their human readable name, via "getDefaultMetrics" and "getDefaultProcessedMetrics"</li>
* <li>the list of segments metadata supported by all functions that have a 'segment' parameter</li>
* <li>the (truly magic) method "getProcessedReport" will return a human readable version of any other report, and include the processed metrics such as
* conversion rate, time on site, etc. which are not directly available in other methods.
* </ul>
* The Metadata API is for example used by the Piwik Mobile App to automatically display all Piwik reports, with translated report & columns names and nicely formatted values.
