  SOGoMailObject
    Parent object: the SOGoMailFolder
    Child objects: SOGoMailBodyPart's
  
  Represents a single mail as retrieved using NGImap4. Since IMAP4 can parse
  MIME structures on the server side, which we map into child objects of the
  message.
  The child objects are accessed using integer IDs, eg:
    /INBOX/12345/1/2/3
  would address the MIME part 1.2.3 of the mail 12345 in the folder INBOX.
