      Generates the standard rules config.

      The rules config should be imported into the app's config.exs

      The rule config may be changed to suit your needs, if new rules are 
      added or you wish the rendering behaviour of current rules to be changed
      this can be done by defining new rendering implementations for those
      rules.
