title: Code Coverage for Typescript using karma-jasmine and istanbul
body: <p>I am trying to get the Code Coverage for my typescript Code in karma framework using Istanbul
  in karma.conf typescript files are included and by karma typescript-preprocessor we  able to do unit testing and code coverage of the typescript code but Code coverage report come for trans piled JavaScript code </p>
  
  <p><strong>How can I get the coverage report for typescript code?</strong></p>
  
  <p>Here is my <code>karma.conf</code> file.</p>
