 * This loader loads documents and type definitions from JSON files.

 * The JSON file can be the result of an introspection query made against a schema:
 *
 * ```js
 * const schema = await loadSchema('schema-introspection.json', {
 *   loaders: [
 *     new JsonFileLoader()
 *   ]
 * });
 * ```
 *
 * Or it can be a `DocumentNode` object representing a GraphQL document or type definitions:
 *
 * ```js
 * const documents = await loadDocuments('queries/*.json', {
 *   loaders: [
 *     new GraphQLFileLoader()
 *   ]
 * });
