/**
* Contains methods that calculate metrics by aggregating log data (visits, actions, conversions,
* ecommerce items).
*
* You can use the methods in this class within {@link Piwik\Plugin\Archiver Archiver} descendants
* to aggregate log data without having to write SQL queries.
*
* ### Aggregation Dimension
*
* All aggregation methods accept a **dimension** parameter. These parameters are important as
* they control how rows in a table are aggregated together.
*
* A **_dimension_** is just a table column. Rows that have the same values for these columns are
* aggregated together. The result of these aggregations is a set of metrics for every recorded value
* of a **dimension**.
*
* _Note: A dimension is essentially the same as a **GROUP BY** field._
*
* ### Examples
*
* **Aggregating visit data**
*
* $archiveProcessor = // ...
* $logAggregator = $archiveProcessor->getLogAggregator();
*
* // get metrics for every used browser language of all visits by returning visitors
* $query = $logAggregator->queryVisitsByDimension(
* $dimensions = array('log_visit.location_browser_lang'),
* $where = 'log_visit.visitor_returning = 1',
*
* // also count visits for each browser language that are not located in the US
* $additionalSelects = array('sum(case when log_visit.location_country <> 'us' then 1 else 0 end) as nonus'),
*
* // we're only interested in visits, unique visitors & actions, so don't waste time calculating anything else
* $metrics = array(Metrics::INDEX_NB_UNIQ_VISITORS, Metrics::INDEX_NB_VISITS, Metrics::INDEX_NB_ACTIONS),
* );
* if ($query === false) {
* return;
* }
*
* while ($row = $query->fetch()) {
* $uniqueVisitors = $row[Metrics::INDEX_NB_UNIQ_VISITORS];
* $visits = $row[Metrics::INDEX_NB_VISITS];
* $actions = $row[Metrics::INDEX_NB_ACTIONS];
*
* // ... do something w/ calculated metrics ...
* }
*
* **Aggregating conversion data**
*
* $archiveProcessor = // ...
* $logAggregator = $archiveProcessor->getLogAggregator();
*
* // get metrics for ecommerce conversions for each country
* $query = $logAggregator->queryConversionsByDimension(
* $dimensions = array('log_conversion.location_country'),
* $where = 'log_conversion.idgoal = 0', // 0 is the special ecommerceOrder idGoal value in the table
*
* // also calculate average tax and max shipping per country
* $additionalSelects = array(
