HOW to Use:
// Create the pagination object
$pagination = new pagination($data, (isset($_GET['page']) ? $_GET['page'] : 1), $perpage);
// Decide if the first and last links should show
$pagination->setShowFirstAndLast(false);
// You can overwrite the default seperator
$pagination->setMainSeperator('');
// Parse through the pagination class
$shopPages = $pagination->getResults();
$pageNumbers = '<div class="pagination">' . $pagination->getLinks($_GET) . '</div>';
