  /**
   * \@name IonicErrorHandler
   * \@description
   * The `IonicErrorHandler` intercepts the default `Console` error handling
   * and displays runtime errors as an overlay when using Ionic's Dev Build Server.
   *
   *
   * ### IonicErrorHandler Example
   *
   * ```typescript
   * import { ErrorHandler, NgModule } from '\@angular/core';
   * import { IonicErrorHandler } from 'ionic-angular';
   *
   * \@NgModule({
   *   providers: [{ provide: ErrorHandler, useClass: IonicErrorHandler }]
   * })
   * class AppModule { }
   * ```
   *
   *
   * ### Custom Error Handlers
   *
   * Custom error handlers can be built to replace the default, or extend Ionic's
   * error handler.
   *
   * ```typescript
   * class MyErrorHandler implements ErrorHandler {
   *   handleError(err: any): void {
   *     // do something with the error
   *   }
   * }
   *
   * \@NgModule({
   *   providers: [{ provide: ErrorHandler, useClass: MyErrorHandler }]
   * })
   * class AppModule { }
   * ```
   *
   * More information about Angular's [`ErrorHandler`](https://angular.io/docs/ts/latest/api/core/index/ErrorHandler-class.html).
