Output logic level value with hysteresis. Transition high when input exceeds setLevel. Only go
low when input is below resetLevel. This can be used to reject low level noise on the input
signal. The default values for setLevel and resetLevel are both 0.0. Setting setLevel to 0.1 and
resetLevel to -0.1 will give some hysteresis. The outputPulse is a single sample wide pulse set
when the output transitions from low to high.
