(MFC) Duplicate curl -u user:password with Chilkat HTTP

Demonstrates how to duplicate a curl command that uses the -u username:password option. (This assumes HTTP Basic Authentication, and Chilkat requires Basic authentication to be over a TLS connection.)

Duplicates the following curl command:

curl https://api.sandbox.paypal.com/v1/oauth2/token \
  -H "Accept: application/json" \
  -H "Accept-Language: en_US" \
  -u "Client-Id:Secret" \
  -d "grant_type=client_credentials"

    //  The AddHeader method corresponds to the curl "-H" argument.
    req.AddHeader("Accept","application/json");
    req.AddHeader("Accept-Language","en_US");

    //  The curl "-d" argument specifies the HTTP request body.  In this case,
    //  we're sending an application/x-www-form-urlencoded request, and therefore
    //  the body contains the URL-encoded query parameters.
    req.AddParam("grant_type","client_credentials");
