docs: Simple schedule generation where startDate and maturityDate are calculated based on referenceDate, spotOffsetDays, startOffsetString and maturityString.
  
  The schedule generation considers short periods. Date rolling is ignored.
  
  @param referenceDate The date which is used in the schedule to internally convert dates to doubles, i.e., the date where t=0.
  @param spotOffsetDays Number of business days to be added to the trade date to obtain the spot date.
  @param startOffsetString The start date as an offset from the spotDate (build from tradeDate and spotOffsetDays) entered as a code like 1D, 1W, 1M, 2M, 3M, 1Y, etc.
  @param maturityString The end date of the last period entered as a code like 1D, 1W, 1M, 2M, 3M, 1Y, etc.
  @param frequency The frequency (as String).
  @param daycountConvention The daycount convention (as String).
  @param shortPeriodConvention If short period exists, have it first or last (as String).
  @param dateRollConvention Adjustment to be applied to the all dates (as String).
  @param businessdayCalendar Business day calendar (holiday calendar) to be used for date roll adjustment.
  @param fixingOffsetDays Number of business days to be added to period start to get the fixing date.
  @param paymentOffsetDays Number of business days to be added to period end to get the payment date.
  @return The corresponding schedule
