Code

<?php

  // This recursion limit could be set from a settings page but 9 seems like a reasonable level.

  // Get type

  // Cast object as array

    // CSS and JS will be directly embedded to insure they are loaded even if the output is not rendered inside a drupal template.
    // This code would only be loaded when someone calls dprint_rx(); and then exit(); 
    // or they call dprx() within the templatepage.tpl.php which has already loaded the css and js.
