title: FullCalendar Resource view, change cell background color
body: <p>I'm using the Full calendar Resource View of jarnokurlin (<a href="https://github.com/jarnokurlin/fullcalendar" rel="nofollow noreferrer">https://github.com/jarnokurlin/fullcalendar</a>), which was an extension of Full calendar of AdamShow. </p>
  
  <p>My issues is I want to indicate the holidays in the time line by changing the cell background color in front of each resource. Different resources may be from different countries so I have to change the colors of the day cells accordingly.</p>
  
  <p>How to do this?</p>
