/**
 * The Live! API lets you access complete visit level information about your visitors. Combined with the power of <a href='http://piwik.org/docs/analytics-api/segmentation/' target='_blank'>Segmentation</a>,
 * you will be able to request visits filtered by any criteria.
 *
 * The method "getLastVisitsDetails" will return extensive data for each visit, which includes: server time, visitId, visitorId,
 * visitorType (new or returning), number of pages, list of all pages (and events, file downloaded and outlinks clicked),
 * custom variables names and values set to this visit, number of goal conversions (and list of all Goal conversions for this visit,
 * with time of conversion, revenue, URL, etc.), but also other attributes such as: days since last visit, days since first visit,
 * country, continent, visitor IP,
 * provider, referrer used (referrer name, keyword if it was a search engine, full URL), campaign name and keyword, operating system,
 * browser, type of screen, resolution, supported browser plugins (flash, java, silverlight, pdf, etc.), various dates & times format to make
 * it easier for API users... and more!
 *
 * With the parameter <a href='http://piwik.org/docs/analytics-api/segmentation/' target='_blank'>'&segment='</a> you can filter the
 * returned visits by any criteria (visitor IP, visitor ID, country, keyword used, time of day, etc.).
 *
 * The method "getCounters" is used to return a simple counter: visits, number of actions, number of converted visits, in the last N minutes.
 *
 * See also the documentation about <a href='http://piwik.org/docs/real-time/' target='_blank'>Real time widget and visitor level reports</a> in Piwik.
