Display a notification message globally.

## When To Use
To display a notification message at any of the four corners of the viewport. Typically it can be
used in the following cases:

- A notification with complex content.
- A notification providing a feedback based on the user interaction. Or it may show some details
about upcoming steps the user may have to follow.
- A notification that is pushed by the application.

## API

- `notification.success(config)`
- `notification.error(config)`
- `notification.info(config)`
- `notification.warning(config)`
- `notification.warn(config)`
- `notification.close(key: String)`
- `notification.destroy()`

The properties of config are as follows:

| Property    | Description                              | Type              | Default  |
| ----------- | ---------------------------------------- | ----------------- | -------- |
| message     | The title of notification box (required) | string\|ReactNode | -        |
| description | The content of notification box (required) | string\|ReactNode | -        |
| className   | Customized CSS class                     | string            | -        |
| style       | Customized inline style                  | Object            | -        |
| btn         | Customized close button                  | ReactNode         | -        |
| icon        | Customized icon                          | ReactNode         | -        |
| key         | The unique identifier of the Notification | string            | -        |
| onClose     | Specify a function that will be called when the close button is clicked | Function          | -        |
| duration    | Time in seconds before Notification is closed. When set to 0 or null, it will never be closed automatically | number            | 4.5      |
| placement   | Position of Notification, can be one of `topLeft` `topRight` `bottomLeft` `bottomRight` | string            | `topRight` |

`notification` also provides a global `config()` method that can be used for specifying the default options. Once this method is used, all the notification boxes will take into account these globally defined options when displaying.

- `notification.config(options)`
```js
notification.config({
  placement: 'bottomRight',
  bottom: 50,
  duration: 3,
});
```
