Create a multipart/alternative MIME Entity

Demonstrates the Chilkat Mime.NewMultipartAlternative method, which initializes the object as an empty multipart/alternative entity. It takes no arguments; the alternative representations are then appended.

Background: multipart/alternative holds several renderings of the same content and lets the client pick the best one it can display — the standard way to send an email as both plain text and HTML. Order matters: parts go from least to most preferred, so the plain-text version comes first and the HTML last, and a client shows the last one it understands.
