Clear an Email Object

Demonstrates the Chilkat Email.Clear method, which removes the current message content — recipients, headers, body representations, attachments, related items, and embedded messages — leaving an empty email object. This example builds a message with a recipient and attachment, clears it, and prints the counts before and after.

Background: Reusing a single Email object across many operations is efficient, but leftover state from a previous message could leak into the next. Clear resets the object completely, giving you a clean slate — the safe way to start a fresh message without allocating a new object.
