  \class QContactId

  \brief The QContactId class provides information that uniquely identifies

  a contact in a particular manager.

  It consists of a manager URI which identifies the manager which contains the contact,

  and the local id of the contact in that manager.

  A "null" QContactId has an empty manager URI, and an invalid QContactLocalId (0).

  \sa QContactLocalId

/*!

  \typedef QContactLocalId

  \relates QContactId

  \brief The QContactLocalId type represents the unique id of a contact within its manager.

  Most operations within a \l QContactManager accept a QContactLocalId.  Some operations

  (involving links to contacts outside a particular manager) also accept a manager URI - this

  combination is stored in a \l QContactId.

  An invalid QContactLocalId is represented by a zero (0) value.
