// Mail interface defines mail to be read.
// This can be a threaded list of messages, or a single message.
//
// String() should return a string representing what the user needs to see
// to further interact with the Mail. For a single message, this should be
// simply the message. For a threaded list of messages, this might be a list
// of all messages in the thread, or possibly a just newest unread message?
//
// Summary() should return a short string that can fit on one line, suitable
// for printing as 1 item in a list on a screen.
// For instance, for a single message:
//     Test Message from Frenata <mr.k.frenata@gmail.com>
