Simple access to session.flash.
Flash is a mechanism using sessions to provide a rotating holder of key/value pairs.
Every request that is made will rotate one step, dropping contents stored two requests ago.
The purpose of this class is to provide an easy way of setting/retrieving from the current flash.
Flash is a way to keep a temporary pairs of keys and values for the duration of two requests, the current and following.
Very vague Example:
On the first request, for example on registering:
flash[:error] = "You should reconsider your username, it's taken already" redirect R(self, :register)
This is the request from the redirect:
do_stuff if flash[:error]
On the request after this, flash[:error] is gone.
