/**
  @short address book entry

  This class represents an entry in the address book.

  The data of this class is implicitly shared. You can pass this class by value.

  If you need the name of a field for presenting it to the user you should use
  the functions ending in Label(). They return a translated string which can be
  used as label for the corresponding field.

  About the name fields:

  givenName() is the first name and familyName() the last name. In some
  countries the family name comes first, that's the reason for the
  naming. formattedName() is the full name with the correct formatting.
  It is used as an override, when the correct formatting can't be generated
  from the other name fields automatically.

  realName() returns a fully formatted name(). It uses formattedName, if set,
  otherwise it constucts the name from the name fields. As fallback, if
  nothing else is set it uses name().

  name() is the NAME type of RFC2426. It can be used as internal name for the
  data enty, but shouldn't be used for displaying the data to the user.
