Sinch Contact Center Visitor Intermediate Client. Creates an iframe and loads the Visitor chat application inside it. Provides simple API functions to instruct the application. Uses cross-origin communication to send command messages between the application and this client. After the script is loaded, 'cvc' library is added to window scope, where the API functions are available.

        cvc.attachEvent("chatState", function(ev){
          if(ev.detail === "completed"){
            // chat completed, lets print out the transcript
            cvc.getDetails(function (ev){
              alert(JSON.stringify(ev.detail.transcript))
            });
          }
