title: How to reverse order in *ngFor?
body: <p>Please help user order module in *ngFor directive.</p>
  
  <p>I install "ngx-order-pipe": "^1.0.2", and use it in app.module.ts:</p>
  
  <pre><code>import { OrderModule } from 'ngx-order-pipe';
  ...
  ..
  
  @NgModule({
    declarations: [
      AppComponent
    ],
    imports: [
      OrderModule,
      ...
      ..
    ],
    providers: [AgendaService],
    bootstrap: [AppComponent]
  })
  export class AppModule { }
  </code></pre>
  
  <p>My template:</p>
  
  <pre><code>&lt;div class="line" *ngFor="let line of agenda | orderBy:'order'; let iLine = index"&gt;
    &lt;div class="left"&gt;
      {{ line.start.trim() }} - {{ line.end.trim() }}  
      = {{line.order}} 
    &lt;/div&gt;       
  &lt;/div&gt;
  </code></pre>
  
  <p>It worked (lines sorted ascending). But i need lines sorted descending.</p>
  
  <p>I try follow:</p>
  
  <pre><code>&lt;div class="line" *ngFor="let line of agenda | orderBy:'-order'; let iLine = index"&gt;
      .....    
  &lt;/div&gt;
  </code></pre>
  
  <p>But it not worked.</p>
