(Chilkat2-Python) Upload to Tumbleweed SecureTransport FTPS Server

Demonstrates how to connect, authenticate, and upload file to a Tumbleweed Secure Transport SSL FTP Server. Instead of providing a login name and password, you pass the string "site-auth" for the username, and an empty string for the password. You must also provide a client-side digital certificate -- as the certificate's credentials and validity are used to authenticate.
