title: How to select multiple date ranges from Fullcalendar?
body: <p>I am trying to make a calendar feature in which a user can block off multiple date ranges by just selecting the start and end dates. I was thinking of using <a href="http://fullcalendar.io/docs/" rel="noreferrer">FullCalendar</a> but I am not sure how to proceed with this. </p>
  
  <p>I did see some examples of how to block some dates from being selected by adding my check on <code>dayClick</code> but these do not deal with date ranges. I would appreciate any help, I am not really looking for an entire source but some suggestions on how to go about this.  </p>
