ELS example: extract two version of ssn with rdt.redact to mask real-time

[cvbmilani]

A constant ask is: Can a mask real time? The answer is to use Entity Services to create two version(Full, Masked) of the ssn and use two paths to protect the Full SSN and the Masked SSN. Hence a call center operator only sees Masked, while HR sees Full. Better yet, to use rdt.redact on the extraction to masked the ssn.

Seems like a straightforward enhancement. Probably this issue should be part of the DHF++ backlog, as that's where coordinated effort on entity-services and the data hub go.
