 * @brief View of a filter (active or inactive) used on the search page.
 * @todo The search filter component needs a pretty heavy rewrite along with the
 *  search.tpl page template. This template includes far too much logic which
 *  could be processed in SearchHandler.inc.php.
 *
 * @uses $filterType string Can be "date" or "text" (default: text)
 * @uses $filterName string
 * @uses $filterValue string
 * @uses $key string The translation key for the field name.
 * @uses $displayIf string Can be "emptyFilter" or "activeFilter".
 * @uses $startYear string Required for filter type "date".
 * @uses $endYear string Required for filter type "date".
