/**  [Description]

    This class allows sending unique events via VCL's
    Application::PostUserEvent().  When the User-Event is dispatched,
    the handler <Event()> is called, which calls the Link provided with
    SetEventHdl().

    The instances are held via Ref-Count until a possibly sent
    event has arrived.  If the target dies before delivery,
    the connection must be severed with SetEventHdl(Link()).
