As in issue #13 an example solution provided by @jrhe an implementation of said feature has been created. As per the discussion in the thread this is only a helper to be able to reach the available options provided in the active_model_serializer gem. usage is as follows: ```ruby get '/some_path' do collection = Collection.all render collection, { meta: { current_page: 5 }, meta_key: :pagination_info } end ``` The return value would be: `{ pagination_info: { current_page: 5 }, collection: [item, item] }` If given without a `meta_key` it would return as: `{ meta: { current_page: 5 }, collection: [item, item] }` Any feedback appreciated. @zph, @olleolleolle and @bjoska
