/**
 * Generate realist mock entities for testing and demo purposes.
 *
 * Import this module in the root AppModule to automatically write demo data into the database on loading of the module.
 * You need to pass providers for {@link DemoDataGenerator} implementations to the `forRoot()` method to register them.
 *
 *```javascript
 *  DemoDataModule.forRoot([
 *    ...DemoChildGenerator.provider({count: 150}),
 *    { provide: DemoUserGeneratorService, useClass: DemoUserGeneratorService }
 *   ])
 * ```
 *
 * In addition to importing the `DemoDataModule` you need to call the {@link DemoDataService}'s `publishDemoData()` method
 * to actually start the data generation.
 * Use `DemoDataGeneratingProgressDialogComponent.loadDemoDataWithLoadingDialog(this.dialog);` passing a `MatDialog` service
 * to display a dialog box to the user and automatically handle the data generation.
 *
 * To implement your own demo data generator, refer to the How-To Guides:
 * - [How to Generate Demo Data]{@link /additional-documentation/how-to-guides/generate-demo-data.html}
