,DayCountConvention
Implementation of ACT/ACT AFB.
Calculates the day count by calculating the actual number of days between startDate and endDate.
A fractional day is rounded to the approximately nearest day.
The day count fraction is calculated using ACT_ACT_AFB convention. The algorithm works as follows:

If the interval from startDate to endDate spans more than a whole year, then
the number of whole years is subtracted from the endDate year and added (as an integer) to the day count fraction.
Here, subtraction of whole year(s) means:
 If the end date is on a February 29th and the resulting day is not in a leap year, it will be set to February 28th of that year (i.e., we preserve "end of month").
 If the end date is on a February 28th of a nonleap year and the resulting day is in a leap year, it will be on February 29th of that year (i.e., we preserve "end of month").
 Otherwise the resulting day has the same day of month and the same month as the end year.
 For the remaining interval the actual number of days is divided by a denominator, where the denominator is 366.0 if February 29th is in between start and end and 365.0 otherwise.
