Create a multipart/mixed MIME Entity

Demonstrates the Chilkat Mime.NewMultipartMixed method, which initializes the object as an empty multipart/mixed entity, clearing any existing content. It takes no arguments; child parts 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/mixed is the container for independent parts shown one after another — the classic "message body plus attachments" layout. Each child is its own distinct content, unlike multipart/alternative (competing renderings of the same thing) or multipart/related (a part and its embedded resources). Start here, then AppendPart a body and AppendPartFromFile the attachments.
