Adapted from https://api.drupal.org/api/drupal/includes%21pager.inc/function/theme_pa...

The purpose of this is to return the HTML to display a "pager", as created from the pager_query() function.

$tags: An array of labels for the controls in the pager. $limit: The number of query results to display per page. $element: An optional integer to distinguish between multiple pagers on one page. $parameters: An associative array of query string parameters to append to the pager links. $quantity: The number of pages in the list.
