Get a Digest Message as an Email Object

Demonstrates the Chilkat Email.GetDigestEmail method, which copies the Nth digest email contained within a multipart/digest into another Email object. The first digest is at index 0; the NumDigests property gives the count. This example loads a digest email and lists each bundled message's subject.

Background: A multipart/digest packs many separate emails into one carrier message — historically used by mailing lists to send a single daily bundle of that day's posts. GetDigestEmail unpacks each member into a full Email object so it can be read or processed individually. This differs from GetAttachedEmail, which extracts messages attached to an ordinary email rather than the members of a digest.
