# This is for use with https://github.com/cerebris/jsonapi-resources
# It was developed with https://github.com/venuu/jsonapi-authorization but it may not be required because it doesn't seem to deal with attributes, just scope and record permissions?
# eg.
# class BaseResource < JSONAPI::Resource
#   include JSONAPI::Authorization::PunditScopedResource
#   include CrewdPolicies::JSONAPIResource
#   abstract
# end
