Create a multipart/related MIME Entity

Demonstrates the Chilkat Mime.NewMultipartRelated method, which initializes the object as an empty multipart/related entity. It takes no arguments; the primary part and its related resources are then appended.

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

Background: multipart/related ties a primary part to the resources it references — most commonly an HTML body and the inline images it embeds via cid: references. Unlike a plain attachment, a related image is displayed within the message rather than listed separately. The HTML part comes first, followed by each referenced resource with a matching Content-ID.
