 * 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 [cordova-plugin-badge docs](https://github.com/katzer/cordova-plugin-badge).
 *
 * ```
 * ionic plugin add https://github.com/katzer/cordova-plugin-badge.git
 * ````
 *
 * @usage
 * ```js
 * Badge.setBadge(10);
 * Badge.increaseBadge();
 * Badge.clearBadge();
