// - the array of elements that are returned by queryFeedHeadlines
// - the length that the caller wants to truncate the content preview to
// - a boolean that indicates if the caller is from an API call
// The field content_preview has been shortened and sanitized, as appropriate
// before the plugin is called. If you want to do your own preview handling
// use the content field and create the preview from that
//NOTE:**** You have to make this a system plugin if you want it to also work
// on API calls. If you just make it a user plugin it will work on web page output
// but not on API calls
