/**
* Generates insights by comparing the report for a given date/period with a different date and calculating the
* difference. The API can exclude rows which growth is not good enough or did not have enough impact.
*
* @param int $idSite
* @param string $period
* @param string $date
* @param string $reportUniqueId eg 'Actions_getPageUrls'. An id like 'Goals_getVisitsUntilConversion_idGoal--4' works as well.
* @param bool|string $segment
* @param int $limitIncreaser Value '0' ignores all increasers
* @param int $limitDecreaser Value '0' ignores all decreasers
* @param string $filterBy By default all rows will be ignored. If given only 'movers', 'new' or 'disappeared' will be returned.
* @param int $minImpactPercent The minimum impact in percent. Eg '2%' of 1000 visits means the change /
* increase / decrease has to be at least 20 visits. Usually the '2%' are based on the total
* amount of visits but for reports having way less visits the metric total is used. Eg A page
* has 1000 visits but only 100 visits having keywords. In this case a minimum impact of '2%' evaluates to 2 and not 20.
* @param int $minGrowthPercent The amount of percent a row has to increase or decrease at least compared to the previous period.
* If value is '20' the growth has to be either at least '+20%' or '-20%' and lower.
* @param int $comparedToXPeriods The report will be compared to X periods before.
* @param string $orderBy Orders the rows by 'absolute', 'relative' or 'importance'.
*
* @return DataTable
*
* @throws \Exception In case a report having the given ID does not exist
* @throws \Exception In case the report exists but does not return a dataTable
