Description

tests for valid social security numbers according to the social security administration. more specifically: -disallows a group to have all 0s -disallows first group to have all 6s -disallows a ssn to begin with 9

note that this does not test for issued ssn's. that would be impossible to implement here, because the high group document is continuously updated on a monthly basis.
