WP_Community_Events::trim_events( array $events )

Prepares the event list for presentation.

Description Description

Discards expired events, and makes WordCamps "sticky." Attendees need more advanced notice about WordCamps than they do for meetups, so camps should appear in the list sooner. If a WordCamp is coming up, the API will "stick" it in the response, even if it wouldn’t otherwise appear. When that happens, the event will be at the end of the list, and will need to be moved into a higher position, so that it doesn’t get trimmed off.
