  # decent_exposure won't currently intuit a collection (plural resource) for you. The SLTD error is 
  # caused by a circular reference between an undeclared collection (which the singular resource attempts
  # to scope from) and the singular resource. To fix this problem, just define the collection:
  expose(:things) { Thing.all }
  # or alternatively, something like:
  # expose(:things) { current_user.things }
  expose(:thing)
