Issue with chattering involving arrays in the Buildings library

[Francesco Casella]

Please check ​Buildings.Controls.Continuous.Examples.SignalRanker. The simulation fails with

LOG_SUCCESS       | info    | The initialization finished successfully without homotopy method.
stdout            | info    | Chattering detected around time 7.45058059692e-13..7.45057922302e-11 (100 state events in a row with a total time delta less than the step size 0.0002). This can be a performance bottleneck. Use -lv LOG_EVENTS for more information. The zero-crossing was: sigRan.y[1] < sigRan.y[1 + 1]
assert            | debug   | Aborting simulation due to chattering being detected and the simulation flags requesting we do not continue further.
