import { BrowserModule } from '@angular/platform-browser';
import { BrowserAnimationsModule } from
    '@angular/platform-browser/animations';


import { AppComponent } from './app.component';
import { NgbModule } from '@ng-bootstrap/ng-bootstrap';

@NgModule({
    bootstrap: [
        AppComponent
    ],
    declarations: [

    ],
    imports: [
        FormsModule,
        BrowserModule,
