[Radiant] Access to session object when creating a behavior

[jsmorris]

I am still learning Ruby, Rails, and Radiant, but I am trying to
develop a new behavior for a custom application that extends Radiant.

I see that have access to request and response objects in the
BaseBehavior, but do I have access to the session object?

I want to make all pages aware of the logged in user, but I am not
sure how to go about doing this with Radiant.

Appreciate any help...
