        Takes model and timeTolerance and sets the time tolerance of zero crossing.
      - bdeSetZeroCrossingThreshold
        Takes model and threshold and sets the zero crossing threshold property. When zero crossing is detected on a function e.g. F, F changes the sign and becomes almost zero. When the absolute value becomes greater than the threshold, the zero-crossing search resumes. This is used to handle functions that get stuck on zero.
