Add reframe db

[benjamin-asdf]

I am not sure how to test it.

[benjamin-asdf]

  (:require [re-frame.interop :refer [ratom]]))

;; -- Application State  --------------------------------------------------------------------------
;;
;; Should not be accessed directly by application code.
;; Read access goes through subscriptions.
;; Updates via event handlers.
(def app-db (ratom {}))

re-frame db might be useful while developing.

Can you bump sci.config in the relevant project? Not sure if this was for nbb or scittle, but welcome to bump them both
