/**
 * @name Is Debug
 * @description
 * Detect if the app is running in debug mode or not.
 * Debug mode is when the app is built and installed locally via xcode / eclipse / the cordova cli etc, compared to release mode when the app was downloaded from the app / play store via an end user.
 *
 * @usage
 * ```typescript
 * import { IsDebug } from '@ionic-native/is-debug';
 *
 * constructor(private isDebug: IsDebug) { }
 *
 * ...
 *
 * this.isDebug.getIsDebug()
 *   .then((isDebug: boolean) => console.log('Is debug:', isDebug))
 *   .catch((error: any) => console.error(error));
 *
 * ```
