Flow & Auth-fw sample

[Upayavira]

I have committed a partly working auth-fw/flow sample. I think it is 
basically there, but I am gettting stuck with:

SessionManager.streamContextFragment: Context 'authentication' not found.

I've never used the session manager (nor sessions for that matter), so 
I'm a bit out of my depth. Could one of you take a look and see if you 
can see how to make it work?

[The one thing I can spot is that cocoon.redirectTo(uri) in FOM_Cocoon 
sets the 'session' value to false, so there appears to be no way to do a 
session aware redirect from flow].
