 * @name Background Geolocation
 * @description
 * This plugin provides foreground and background geolocation with battery-saving "circular region monitoring" and "stop detection". For
 * more detail, please see https://github.com/mauron85/cordova-plugin-background-geolocation
 *
 * @usage
 *
 * BackgroundGeolocation must be called within app.ts and or before Geolocation. Otherwise the platform will not ask you for background tracking permission.
 *
 * ```typescript
 * import { BackgroundGeolocation, BackgroundGeolocationConfig } from '@ionic-native/background-geolocation';
 *
 * constructor(private backgroundGeolocation: BackgroundGeolocation) { }
 *
 * ...
 *
 * const config: BackgroundGeolocationConfig = {
 *             desiredAccuracy: 10,
 *             stationaryRadius: 20,
 *             distanceFilter: 30,
 *             debug: true, //  enable this hear sounds for background-geolocation life-cycle.
 *             stopOnTerminate: false, // enable this to clear background location settings when the app terminates
 *     };
 *
 * this.backgroundGeolocation.configure(config)
 *   .subscribe((location: BackgroundGeolocationResponse) => {
 *
 *     console.log(location);
 *
 *     // IMPORTANT:  You must execute the finish method here to inform the native plugin that you're finished,
 *     // and the background-task may be completed.  You must do this regardless if your HTTP request is successful or not.
 *     // IF YOU DON'T, ios will CRASH YOUR APP for spending too much time in the background.
 *     this.backgroundGeolocation.finish(); // FOR IOS ONLY
 *
 *   });
 *
 * // start recording location
 * this.backgroundGeolocation.start();
 *
 * // If you wish to turn OFF background-tracking, call the #stop method.
 * this.backgroundGeolocation.stop();
