[security-dev] Merged in Social code into PL workspace

[Anil Saldhana]

Shane,
   recently I merged in the social login code under "social".  This is 
plain vanilla code for login using facebook and google. I need to move 
some code for twitter login.

Next we are going to move the federation code under "federation". This 
will provide the SAML object model/parsing/writing.

Since I have OAuth2 implementation, I am wondering whether I should just 
merge into social or keep a separate module called "oauth". I am leaning 
toward the latter.

Regards,
Anil
