title: How to set locale for numbers in angular 2.0
body: <p>The number format in Swiss German is like "100'000.00" (not "100,000.00"). How can I change that? I tried to change the settings in number_pipe.js from en-US to de-CH without success.</p>
  
  <pre><code>var defaultLocale: string = 'de-CH';</code></pre>
  
  <p>Is there a workaround or do I have to implement my own pipe?</p>
