GF_Results_Cache
Manages the entry results cache expiry and rebuild.
GF_Results_Cache::get_results() will attempt to calculate the results inside the time_limit arg. If incomplete then a WP Cron task is kicked off. If the cron task is unable to finish within time_limit_cron then another task is scheduled until the results are complete.
