Check if a MIME Tree Contains Signed Parts

Demonstrates the Chilkat Mime.ContainsSignedParts method, which returns whether the currently visible MIME tree contains a complete detached or opaque CMS/PKCS #7 signed entity. It takes no arguments.

Note: The file path is relative to the application's current working directory. Absolute paths may also be used. Supply the path to your own file.

// Important: Don't forget to include the call to System.loadLibrary
