Check if a MIME Entity is multipart/alternative

Demonstrates the Chilkat Mime.IsMultipartAlternative method, which returns whether the Content-Type is exactly multipart/alternative. 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: Recognizing multipart/alternative matters because its children are the same content in different formats — you display one (usually the last renderable), not all of them. That is the opposite of multipart/mixed, where every child is shown.
