   * ```
    *      <script src="pin-sdk.js"></script>

    *        PDK.init({

    * The best place to put this code is right before the closing
    * `</body>` tag.
    *
    * - Asynchronous Loading -
    *
    * The library makes non-blocking loading of the script easy to use by
    * providing the `pAsyncInit` hook. If this global export function is defined, it
    * will be executed when the library is loaded:
    * ```
    *     <div id="p-root"></div>
    *     <script>
    *       window.pAsyncInit = function() {
    *         PDK.init({
    *           appId  : 'YOUR APP ID',
    *           cookie : true // enable cookies to allow the server to access the session
    *         });
    *       };
    *
    *       (function() {
    *         var e = document.createElement('script');
    *         e.src = 'pin-sdk.js';
    *         e.async = true;
    *         document.getElementById('p-root').appendChild(e);
