Breaking Change
Hi `fanfou-sdk3`!
- API changed, we are using Promise instead of callbacks.
- `ff.up()` has been removed.
**Example**
javascript
ff.get('/statuses/home_timeline', {})
.then(res => console.log(res))
.catch(err => console.log(err))
ff.post('/statuses/update', {status: 'post test'})
.then(res => console.log(res))
.catch(err => console.log(err))
ff.upload('/photos/upload', {photo: fs.createReadStream(path), status: 'unicorn'})
.then(res => console.log(res))
.catch(err => console.log(err))
