+ * 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();
