Specify types in the main export

[Arual90]

Flow is unable to retrieve the types if i import the functions like this:
import {api} from '@contactlab/appy'

But works if the import is written like this:
import api from '@contactlab/appy/dist/api'

@Arual90 let's try something like:

// src/api/index.js
// ----------------
// ...

export type Config = {| ...
export type ApiFn = (m: Method, a: string, t: string, b: ?RequestOptions) ...

// ...

// src/index.js
// ----------------
// ...

import type {Config, ApiFn} from './api';
import type {RequestFn} from './request';

import request from './request';
import api from './api';

interface Appy {
  request: RequestFn;
  api: (config: Config) => ApiFn; 
}

export default ({
  request,
  api
}: Appy);
