Check if a MIME Entity is multipart/related

Demonstrates the Chilkat Mime.IsMultipartRelated method, which returns whether the Content-Type is exactly multipart/related. 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.

Background: multipart/related signals that the parts belong together — typically an HTML body plus the inline images it references by Content-ID. Detecting it tells your code the non-primary parts are embedded resources, not standalone attachments to list.
