Retrieve a property that indicated by the selector from an object.

If the property does not exists returns `undefined`.

```js
|
|
const select = (from, selector) =>
|
|
selector.split('.').reduce((prev, cur) => prev && prev[cur], from);
|
|
|
|
// const obj = {selector: {to: {val: 'val to select'}}};
|
|
// select(obj, 'selector.to.val'); -> 'val to select'
|
|
```
