    //  This example requires the Chilkat API to have been previously unlocked.
    //  See Global Unlock Sample for sample code.

    //  This example will send a POST with HTTP Basic Authentication to 
    //  https://gw-fatoora.zatca.sa/e-invoicing/simulation/invoices/clearance/single

    //  NOTE: At the time of this writing, I don't know for sure if the above URL is correct.
    //  
    //  The body of the POST will contain JSON formatted as such:

    //  {
    //    "summary": "Standard Invoice",
    //    "value": {
    //      "invoiceHash": "PEx8bNFcEMEpHzUVvQntQI6ot8eFqTT/l59b+H1HqX4=",
    //      "uuid": "16e78469-64af-406d-9cfd-895e724198f0",
    //      "invoice": "PD94bWwgdmVyc2lvbj0iMS4wIiBlbmNvZGluZz0iVVRGLTgiPz4KPEl....."
    //    }
    //  }

    //  The above JSON is created from the signed XML invoice, such as the following:

    //  *** Look at the above base64 data for the invoiceHash and uuid.  These values are found in the invoice as shown below.
    //  *** We'll write code to load the signed invoice into a Chilkat XML object, grab the invoice hash and the uuid,
    //  *** and then construct the above JSON, which will then be sent in a POST.  (See below...)
