I have just replaced `react-router` from v3 to v4.  

But I am not sure how to programmatically navigate in the member function of a `Component`.
i.e in `handleClick()` function I want to navigate to `/path/some/where` after processing some data.
I used to do that by:

```js
import { browserHistory } from 'react-router'
browserHistory.push('/path/some/where')

```

But I can't find such interfaces in v4.  

How can I navigate using v4?
