Creates a new event loop instance

```php
$loop = React\EventLoop\Factory::create();
```

This method always returns an instance implementing `LoopInterface`,
the actual event loop implementation is an implementation detail.

This method should usually only be called once at the beginning of the program.

@return LoopInterface
Creates a new event loop instance
