/**
 * Usage:
 *    This file contains the configuration logic used for third party integrations.
 *    At a minimum, this file will provide the CSS and JS files required to properly
 *    display an integrated page.  This will help third parties maintain a basic 
 *    directv.com look and feel during directv.com production downtime.
 *
 *    By default, this file will configure the CDN as 'cdn.directv.com' and the host
 *    as 'www.directv.com'.  To alter these values, append any of the following parameters 
 *    to the JS import statement:
 *    - cdnUrl: The URL of the target CDN server(s)
 *    - hostUrl: The target host from which to load the integration API.
 *    
 *    Example usage (useful for local testing):
 *
 *    <script type="text/javascript" src="//local.directv.com:7001/resources/js/integration/integration.js?cdnUrl=local.directv.com:7001&useGeneric=true&hostUrl=local.directv.com:7001"></script> 
 *
 *    Notes:
 *    1) The path to the file is /resources/js/integration/integration.js
 *    2) Parameter values: 
 *      - The cdn URL was set to the local installation: cdnUrl=local.directv.com:7001
 *      - The generic, non-prototype API was requested: useGeneric=true
 *      - The host was changed to the local installation: hostUrl=local.directv.com:7001
 *
