[security-editors] SAML Basics presentation

Here is the presentation I gave last week at the JA-SIG conference.  Feel 
free to use this yourselves; please just retain 
acknowledgments/credits.  Thanks!  (Jeff, I think you said you were willing 
to put this on the SSTC page...)  If you see any errors, I'm happy to 
maintain it.  It will probably need a syntax example overhaul fairly soon.
