title: Can I use Angular-cli with babel transforms
body: <p>My project is a hybrid AngularJS / Angular project and we are using gulp to perform the following transformation on the Angular part.
  TS -> ES6 -> BABEL (ES5+) -> Rollup or SystemJS
  And alot of gulp watch and caching and Map-magic</p>
  
  <p>I would like this to be more standard using angular cli but cannot find a way to do the babel transform in angular cli. I want it to be able to gradually move to ES6 and beyond as supported platforms allow but also want to keep map files working.</p>
  
  <p>Is there a way to tie Babel into Angular-cli and keep map files through the whole process?</p>
  
  <p>I have tried a broccoli build before I went with gulp but could not get all plugins to work with map files there and since Angular Cli is based on broccoli I can't find a way.</p>
  
  <p>Please help out. :)</p>
