Description:

-------------------------------
CC_Expired version 1.3.1
-------------------------------
Returns 1 if the credit card will have expired by CheckDate, 0 if not.

Credit card hasn't expired until after the CheckDate month is later than the ExpirationDate month (so in December of 2007, an expiration date of 12/07 is still valid).

Expiration dates < 1970 or > 2069 will return an error.

Accepts dates in the form:
M/Y
M/YY
M/YYYY

MM/Y
MM/YY
MM/YYYY

MY
MMY
MMYY
MYYYY
MMYYYY

"." (period) and "-" may be substituted for "/"

This function does not accept dates in the format "MYY" since there are cases where you cannot distinguish MYY and MMY (112, 102, etc.)

All characters but 1234567890, "/", "-" and "." are ignored.
