Check if a MIME Entity is multipart/mixed

Demonstrates the Chilkat Mime.IsMultipartMixed method, which returns whether the Content-Type is exactly multipart/mixed. 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/mixed is the "body plus attachments" layout, so identifying it tells you the children are independent parts to be handled separately rather than competing renderings. It is the specific counterpart to the general IsMultipart.
