-- This function does three things:
--
-- * Creates the route datatype YosogrRoute. Every valid URL in your
-- application can be represented as a value of this type.
-- * Creates the associated type:
-- type instance Route Yosogr = YosogrRoute
-- * Creates the value resourcesYosogr which contains information on the
-- resources declared below. This is used in Handler.hs by the call to
-- mkYesodDispatch
--
-- What this function does *not* do is create a YesodSite instance for
-- Yosogr. Creating that instance requires all of the handler functions
-- for our application to be in scope. However, the handler functions
-- usually require access to the YosogrRoute datatype. Therefore, we
-- split these actions into two functions and place them in separate files.
