Validate all dates associated with Japanese bonds

Introduced in release: 1.0
Component: Non-US (developed mkts)
Purpose: Validates the given dates needed for the Japanese bonds calculations. Checks that settlement date, dated/issue date, first coupon date, last coupon date, and maturity date are valid dates. If optional dates are not provided it creates them. It also checks the following relationships between the dates:

 Last coupon date is less than maturity date.
 Dated/issue date is optional.
 First coupon date not allowed if dated/issue date is not given.
 First coupon date is optional unless dated/issue date creates an
   odd first coupon.
 Settlement date is greater than or equal to dated/issue date.
 Settlement date is less than maturity date.
 Dated/issue date is less than first coupon date.
 Dated/issue date is less than maturity date.
 First coupon date and last coupon date are in sync.  If last coupon
   date is not given, it will be one period less than maturity date.

Results: The value of the function is true (1) if the dates are valid. The value of the function is false (0) if the dates are invalid. The variable status will contain the reason it is invalid.

Error Conditions: The variable status contains a non zero value upon returning from the function when the inputs contain an error. Where x and y are single digits representing different dates as follows:

 1 = maturity date
 2 = dated/issue date
 3 = first coupon date
 6 = last coupon date
 7 = settlement date

The errors are:

 110x = bad year in date
 120x = bad month in date
 130x = bad day in date
 150x = required date not given
 20xy = date x is not less than date y
 21xy = date x is not less than or equal to date y
 22xy = date x is not in sync with date y
