    Class StairCase

    It will use 1-down-1-up before first reversal.

    const staircase = new StairCase({
      start: 0,
      step: 1,
      down: 3,
      up: 1,
      reversal: 3,
      min: 0,
      max: 3,
    });
    for (const value of staircase) {
      console.log(value);
      staircase.response(true); // set current trial response to calculate next value
    }
