title: angular and cron expressions
body: <p>Im looking for some help how to parse in angular client to cron expression and how to translate a cron expression im receiving from the server.
  I already saw Later.js and angular.cron-jobs but the first one is doing only one thing ( parsing from cron expression) and the second one is UI component and Im not looking for an UI component.</p>
  
  <p>any suggestion?</p>
