Aggregate data for multiple (groups) of websites
|Reported by:||matt||Owned by:|
Placeholder ticket for processing aggregated reports for multiple websites.
For example, API functions could accept idSite=1,2,3,4 to return "top keywords" for the websites 1,2,3,4. This would be a useful feature for large Piwik setups, where one customer would "own" several websites and would like to see aggregated stats for all his/her websites.
