(Swift 2) Forward by Attaching the Existing Email to a New Email

Demonstrates how to forward an email by attaching the email to a new email. This example uses the AttachEmail method, which is new in Chilkat v9.5.0.87.

This example reads an email from an IMAP server, attaches the email to a new email, and sends the new email.
