Add fetching

[Asherlc]

It would be great if we could find records simpler, and abstract away the manual work of building parameters for contentful querying, i.e.:

new ArticleParams(
  {
    parentPage: 'ford-mustang'
  },
  {
    order: { publicationDate: 'desc' },
    page: 1,
    limit: 10,
    locale: 'es'
  }
});
