DESCRIPTION

tie takes three arguments, a button b and two valuators v1 and v2.  Whenever the button is queued, the valuators are also queued.  If the button is queued, whenever the button changes state, three entries are made in the queue, recording the current state of the button and the current positions of each valuator.  One valuator can be tied to a button by making v2 = 0.  A button can be untied by making both v1 and v2 zero.  v1 will appear before v2 in the event queue; both are preceded by b.
