title: Include Bower or NPM Component in Angular 2/4 cli Project
body: <p>I'm starting a simple Angular 4 project using the cli, and want to include a package from either NPM or Bower - the package in question is Multi Step Form (<a href="https://github.com/troch/angular-multi-step-form" rel="nofollow noreferrer">https://github.com/troch/angular-multi-step-form</a>). I know I have to add it to the @NgModule class (previously angular.module, right?) but no matter what I try, Angular is either unable to see the module (with Bower), or gives an error message <code>Can't resolve 'angular' in [path-to-multi-step-form/dist/commonjs]</code></p>
  
  <p>Here is the app.module.ts file:</p>
  
  <pre><code>import { BrowserModule } from '@angular/platform-browser';
  import { NgModule } from '@angular/core';
  
  import { AppComponent } from './app.component';
  
  @NgModule({
    declarations: [
      AppComponent
    ],
    imports: [
      BrowserModule
    ],
    providers: [],
    bootstrap: [AppComponent]
  })
  export class AppModule { }
  </code></pre>
  
  <p>and here's the app.component.ts file:</p>
  
  <pre><code>import { Component } from '@angular/core';
  
  @Component({
    selector: 'app-root',
    templateUrl: './app.component.html',
    styleUrls: ['./app.component.scss']
  })
  export class AppComponent {
    title = 'app';
  }
  </code></pre>
  
  <p>Can anyone tell me where / how to include components into Angular 2/4 cli projects? I'm tearing my hair out and feeling pretty dumb since I've been working with Angular for a while now... :/</p>
