Out Roll Circulate can be done from any Line, anywhere, if
    the caller designates who is preferred as the 'Out-Roller'.  For
    example, from Out-Facing Lines, the caller could say 
Prefer the
    End Boy for an Out Roll Circulate.  In this case, the End Boy
    does a Circulate (or a Trade to the far End), as the Others
    Flip (180°) one position toward the 'preferred' End's original position.
