Append a Part to a Multipart MIME Entity

Demonstrates the Chilkat Mime.AppendPart method, which appends a copy of another Mime as the last direct child. The only argument is the source Mime. Chilkat copies it, so later changes to the source do not affect the appended part.

Background: This is the general way to build up a multipart entity from parts you construct yourself — a text body, an HTML body, a nested multipart. Because it appends a copy, you can reuse and modify the source object afterward, or append it more than once, without surprises. For attaching a file directly, AppendPartFromFile is more convenient.
