Cross-orgin requests with JSONP

JSONP is a method for sending JSON data without worrying about cross-domain issues. This is sometimes needed when calling third-party APIs that don't come with appropriate CORS settings.

import jsonp from 'superagent-jsonp';
import { Resource } from 'rest-hooks';

export default class ArticleResource extends Resource {
  readonly id: number | undefined = undefined;
  readonly content: string = '';

  pk() {
    return this.id;
  }
  static urlRoot = 'http://test.com/article/';

  // OPERATIVE LINE HERE
  static fetchPlugin = jsonp;
}

Using the jsonp plugin for superagent makes this quite easy.
