title: Reexport class in Typescript
body: <p>I have two classes in two files.</p>
  
  <pre><code>//a.ts
  export class A{}
  
  //b.ts
  export class B{}
  </code></pre>
  
  <p>How I can build file <code>c.ts</code> from which I could import both classes?</p>
  
  <pre><code>import {A, B} from "c";
  </code></pre>
  
  <p>instead of</p>
  
  <pre><code>import {A} from "a";
  import {B} from "b";
  </code></pre>
  
  <p>I want to make kind of export facade.
  How to reexport type?</p>
