Generates a reusable pager for lists of data.

Usage:

1. Set your data as follows:

$limit = 20;
$num = isset ($this->params[0])
    ? $this->params[0] // from the URL, e.g. /myapp/handler/#
    : 1;
$offset = ($num - 1) * $limit;

$items = MyModel::query ()->fetch ($limit, $offset);
$total = MyModel::query ()->count ();

$data = array (
    'limit' => $limit,
    'total' => $total,
    'items' => $items,
    'count' => count ($items),
    'single' => __ ('page'),
    'plural' => __ ('pages'),
    'url' => '/myapp/handler/%d'
);

echo $tpl->render ('myapp/view', $data);

2. In your template

{! navigation/pager
    ?style=text
    &url=[url]
    &total=[total]

    ?style=text
    &url=[url]
    &total=[total]
    &count=[count]
    &limit=[limit]
    &label=pages !}

Numeric pager:

{! navigation/pager
    ?style=numbers

{! navigation/pager
    ?style=numbers
    &url=[url]

    &extra[/search]=Search !}
