13 This function preceeds and appends the output of the given 'content' function with page selection links. The passed selector will be modified to show only a limited amount ('per_page') of items. The currently displayed page will be determined directly by cgi.params, and not via the param.get(...) function, in order to pass page selections automatically to sub-views.
