Safe member access with initial value assignment.

# Ensure-Key

*Lets you access members of an object safely (will be added if missing and initialized to a value you provide).*

**How to use:**

```
import './Ensure'; 

const registry = {}; 

registry.ensure('abc', {}).ensure('items', []).push(123); 

console.log(registry);  // --> { abc: { items: [ 123 ] } }
```

The ensure method is added to the Object prototype and is thus available on every object. 
It is hidden from enumeration (to not cause interferences with environments).
