Get an FTP Listing Entry's Group

Demonstrates the Chilkat Ftp2.GetGroup method, which returns the group name or identifier of a cached directory-listing entry. The only argument is a zero-based index. The value is empty when the server does not provide group metadata.

Background: The group is the counterpart to the owner in Unix-style ownership, driving the "group" permission bits. Like the owner, it is only present when the server's listing format includes it, and may be reported as a numeric GID. An empty value simply means the metadata was not provided.
