A proof-of-concept extension to help with statistics performance for application sending a lot of email. The idea is that this logic will eventually make its way into Preside core (see PRESIDECMS-2749).
DO NOT USE! (OR AT YOUR OWN RISK)
The extension adds a pair of summary tables to collect count summaries for email clicks, opens, etc. in time buckets of one hour.
It then replaces all statistic querying logic in Preside to use these tables.
The extension includes a db data migration to populate these tables from existing data. If your application has a lot of data, expect/account for this to take a VERY long time.
