title: Cron to human readable string
body: <p>I am using Quartz with Java to schedule jobs. One thing is that i store cron expressions on a database and i would like to present them to a user but in a more readable form. So i was wondering if there is a utility that could convert a cron expression into a human readable string. Something like :</p>
  
  <p>""0 30 10-13 ? * WED,FRI" 
   will become 
  "Fires at 10:30, 11:30, 12:30, and 13:30, on every Wednesday and Friday."</p>
