ms_doy2md calculates the month and day of month (mday) for a given year and day of year (jday).

       ms_md2doy calculates the day of year (jday) for a given year, month and day of month (mday).

       For both routines the expected and resulting ranges for each value are:

       year  : 1900 - 2100
       jday  : 1 - 366
       month : 1 - 12
       mday  : 1 - 31

       A day of year of 366 corresponds to the last day of a leap year.
