iband7: IBP banding data entry system

Date is encoded as “MMDD”. The year is taken from the name of the data set.

In MAWS sets, the date to be output in the encounter record is the date of the actual encounter. During months October, November, and December, the year will be one less than the year taken from the file name. For example, in set CHAF-2004-3, if an encounter took place on date 10/15, the output date will be 20031015, not 20041015.
