Use render props instead of HOC-style `connect`?

First off, thank you for this library, it is awesomely simple!

I've been toying with `react-apollo` and the new `` and `` components, and they are really nice in terms of making data declarative, allowing you to co-locate data requirements inside your components.

I was thinking it would be really nice is `react-refetch` was architected similarly. Instead of `connect(mapPropsToRequests, Component)`, it would be cool do to:

```js

{(fetch) => (
return fetch.pending ? (

) : fetch.rejected ? (

) : (

)
)}

```

Or even, for non-GET methods, offer a mutation API:

```js

{(updateUser, fetch) => (
return fetch.rejected ? (

) : (
Save
)
)}

```

What do you think?
