   * @description
   * Get the number of business day periods between the given dates.
   * Business days being days that arent in the weekend.
   * Like `differenceInCalendarDays`, the function removes the times from
   * the dates before calculating the difference.
   *
   * @param {Date|Number} dateLeft - the later date
   * @param {Date|Number} dateRight - the earlier date
   * @returns {Number} the number of business days
   * @throws {TypeError} 2 arguments required
   *
   * @example
   * // How many business days are between
   * // 10 January 2014 and 20 July 2014?
   * var result = differenceInBusinessDays(
   *   new Date(2014, 6, 20),
   *   new Date(2014, 0, 10)
   * )
   * //=> 136
