Check if a MIME Entity is Multipart

Demonstrates the Chilkat Mime.IsMultipart method, which returns whether the Content-Type begins with multipart/. 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: The first question when processing a message is usually whether it is a single part or a container of parts, because that decides whether you read the body directly or iterate children. IsMultipart answers it for any of the multipart subtypes at once; use the more specific predicates when the exact subtype matters.
