* This API is the <a href='http://piwik.org/docs/analytics-api/metadata/' target='_blank'>Metadata API</a>: it gives information about all other available APIs methods, as well as providing
* human readable and more complete outputs than normal API methods.
*
* Some of the information that is returned by the Metadata API:
* <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.</li>
* <li>the method "getSuggestedValuesForSegment" returns top suggested values for a particular segment. It uses the Live.getLastVisitsDetails API to fetch the most recently used values, and will return the most often used values first.</li>
* </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.
* More information on the <a href='http://piwik.org/docs/analytics-api/metadata/' target='_blank'>Metadata API documentation page</a>
