/**
 * Class Pakkelabels
 *
 * Usage:
 * ----------------
 * The first thing required is to login
 * $label = new Pakkelabels('api_user', 'api_key');
 *
 * This will login and fetch the required token.
 * The token is then automatically added to any subsequent calls.
 *
 * To see the generated token you can use:
 * echo $label->getToken();
 *
 * Examples:
 * ----------------
 * // Get all Post Danmark labels shipped to Denmark
 * $labels = $label->shipments(array('shipping_agent' => 'pdk', 'receiver_country' => 'DK'));
 *
 * // Display the PDF for a specific label
 * $base64 = $label->pdf(31629);
 * $pdf = base64_decode($base64);
 * header('Content-type: application/pdf');
 * header('Content-Disposition: inline; filename="label.pdf"');
 * echo $pdf;
