Module designed for PrestaShop 1.5 and 1.6 stores.

Note: In addition to optimization, the module also clears statistical data.
Table optimization may take some time, so the server must allow extended script execution time.
The module settings include CRON links to fully automate the process.

During tests on active stores, database size was reduced by up to ~90% (from ~210MB down to ~22MB), making backups much easier.
