# A class that represents the current session, as opposed to just a Hash.
# Generally, this can act like a Hash for setting and accessing values stored in the session.
# It provides a few useful additions:
#
# * Your app can extend this to provide an app-specific API around the session.
# * There is direct access to commonly-used data stored in the session, such as the flash.
