/**
 * The **Archive** class is used to query cached analytics statistics
 * (termed "archive data").
 *
 * You can use **Archive** instances to get data that was archived for one or more sites,
 * for one or more periods and one optional segment.
 *
 * If archive data is not found, this class will initiate the archiving process. [1](#footnote-1)
 *
 * **Archive** instances must be created using the {@link build()} factory method;
 * they cannot be constructed.
 *
 * You can search for metrics (such as `nb_visits`) using the {@link getNumeric()} and
 * {@link getDataTableFromNumeric()} methods. You can search for
 * reports using the {@link getBlob()}, {@link getDataTable()} and {@link getDataTableExpanded()} methods.
 *
 * If you're creating an API that returns report data, you may want to use the
 * {@link createDataTableFromArchive()} helper function.
 *
 * ### Learn more
 *
 * Learn more about _archiving_ [here](/guides/all-about-analytics-data).
 *
 * ### Limitations
 *
 * - You cannot get data for multiple range periods in a single query.
 * - You cannot get data for periods of different types in a single query.
 *
 * ### Examples
 *
 * **_Querying metrics for an API method_**
 *
 *     // one site and one period
 *     $archive = Archive::build($idSite = 1, $period = 'week', $date = '2013-03-08');
 *     return $archive->getDataTableFromNumeric(array('nb_visits', 'nb_actions'));
 *
 *     // all sites and multiple dates
 *     $archive = Archive::build($idSite = 'all', $period = 'month', $date = '2013-01-02,2013-03-08');
 *     return $archive->getDataTableFromNumeric(array('nb_visits', 'nb_actions'));
 *
 * **_Querying and using metrics immediately_**
 *
 *     // one site and one period
 *     $archive = Archive::build($idSite = 1, $period = 'week', $date = '2013-03-08');
 *     $data = $archive->getNumeric(array('nb_visits', 'nb_actions'));
 *
 *     $visits = $data['nb_visits'];
 *     $actions = $data['nb_actions'];
 *
 *     // ... do something w/ metric data ...
 *
 *     // multiple sites and multiple dates
 *     $archive = Archive::build($idSite = '1,2,3', $period = 'month', $date = '2013-01-02,2013-03-08');
 *     $data = $archive->getNumeric('nb_visits');
 *
 *     $janSite1Visits = $data['1']['2013-01-01,2013-01-31']['nb_visits'];
 *     $febSite1Visits = $data['1']['2013-02-01,2013-02-28']['nb_visits'];
 *     // ... etc.
 *
 * **_Querying for reports_**
 *
 *     $archive = Archive::build($idSite = 1, $period = 'week', $date = '2013-03-08');
 *     $dataTable = $archive->getDataTable('MyPlugin_MyReport');
 *     // ... manipulate $dataTable ...
 *     return $dataTable;
 *
 * **_Querying a report for an API method_**
 *
 *     public function getMyReport($idSite, $period, $date, $segment = false, $expanded = false)
 *     {
 *         $dataTable = Archive::createDataTableFromArchive('MyPlugin_MyReport', $idSite, $period, $date, $segment, $expanded);
 *         return $dataTable;
 *     }
 *
 * **_Querying data for multiple range periods_**
 *
 *     // get data for first range
 *     $archive = Archive::build($idSite = 1, $period = 'range', $date = '2013-03-08,2013-03-12');
 *     $dataTable = $archive->getDataTableFromNumeric(array('nb_visits', 'nb_actions'));
 *
 *     // get data for second range
 *     $archive = Archive::build($idSite = 1, $period = 'range', $date = '2013-03-15,2013-03-20');
 *     $dataTable = $archive->getDataTableFromNumeric(array('nb_visits', 'nb_actions'));
 *
 * <a name="footnote-1"></a>
 * [1]: The archiving process will not be launched if browser archiving is disabled
 *      and the current request came from a browser.
