Shifts a clocked expressions to undo a delay as part of the synchronous language elements.
backSample(u, shiftCounter, resolution)
Real x=sample(time, u); // Ticks at 0, 3/10, 6/10 with values corresponding to time Real x2=shiftSample(x, 1, 3); // Ticks at 1/10 with value 0/10, and at 4/10 with value 3/10 etc Real x3=backSample(x2, 1, 3); // Same as x.
