Serialize MIME to a String

Demonstrates the Chilkat Mime.GetMime method, which serializes and returns the complete MIME entity — headers, body, multipart boundaries, and all descendants — as a string. It takes no arguments.

Background: This produces the finished MIME text ready to send, store, or hand to another component — the inverse of loading. The whole tree is emitted, including generated multipart boundaries. Because it returns a string, it is best for text-safe content; when the body may contain raw binary bytes, serialize with GetMimeBd to a BinData instead so nothing is altered.
