added nuget package Nancy.Viewengines.Razor
added "history" as a Razor view to Archving sample. Getting an exception on launch.

Exception stack trace: https://gist.github.com/anonymous/3b3d618a3c07a184ea81
Expected behavior is to throw an error for missing API_KEY and API_SECRET.
Once you enter any number in the Samples/Archiving/App.config as the API_KEY,
and any string as the API_SECRET, the application should launch fine. Then
visiting http://localhost:8080/history should render a page that says "Hello
World"
