/**
 * @name Badge
 * @description
 * The essential purpose of badge numbers is to enable an application to inform its users that it has something for them — for example, unread messages — when the application isn’t running in the foreground.
 *
 * Requires Cordova plugin: cordova-plugin-badge. For more info, please see the [Badge plugin docs](https://github.com/katzer/cordova-plugin-badge).
 *
 * @usage
 * ```typescript
 * import { Badge } from '@ionic-native/badge/ngx';
 *
 * constructor(private badge: Badge) { }
 *
 * ...
 *
 * this.badge.set(10);
 * this.badge.increase(1);
 * this.badge.clear();
 * ```
