title: Angular2 Pipe can't find the name
body: <p>I made a Pipe as follow:</p>
  <pre class="lang-ts prettyprint-override"><code>import {Pipe, PipeTransform} from '@angular/core';
  import { Radio } from '../../models/radio';
  @Pipe({
      name: 'radioFilter'
  })
  export class radioFilterPipe  implements PipeTransform {
  
      transform(value: Radio[], args: string[]): any {
  
          let filter = args[0].toLocaleLowerCase();
          return filter ? value.filter(radio =&gt; radio.station.text.toLocaleLowerCase().indexOf(filter) != -1) : value;
      }
  }
  </code></pre>
  <p>and in my component I added the following code:</p>
  <pre class="lang-ts prettyprint-override"><code>import { radioFilterPipe } from './grid.station.pipe';
  
  // pipes: [radioFilter],
  </code></pre>
  <p>but I get a compile error:</p>
  <blockquote>
  <p>error TS2304: Cannot find name 'radioFilter'. What am I doing wrong??</p>
  </blockquote>
