Demonstrates how to send a simple SOAP request. Rust

// Also see Chilkat's Online WSDL Code Generator
// to generate code and SOAP Request and Response XML for each operation in a WSDL.

//             <dat:dNum>99.0</dat:dNum>
//         </dat:NumberToDollars>
//     </soapenv:Body>
// </soapenv:Envelope>
