-- This is where we define all of the routes in our application. For a full
-- explanation of the syntax, please see:
-- This function does three things:
-- * Creates the route datatype TicTacToeRoute. Every valid URL in your
-- application can be represented as a value of this type.
-- * Creates the associated type:
-- type instance Route TicTacToe = TicTacToeRoute
-- * Creates the value resourcesTicTacToe 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
-- TicTacToe. 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 TicTacToeRoute datatype. Therefore, we
-- split these actions into two functions and place them in separate files.

-- Please see the documentation for the Yesod typeclass. There are a number
