title: How to add multiple business hours in fullCalendar?
body: <p>Is there any way to set multiple business hours, or grey out certain time ranges in FullCalendar's agenda view? I'm searching the google for hours, but I didn't find any working answer. </p>
  
  <p>Here's what I've tried: </p>
  
  <pre><code>businessHours:
          [
          {
           start: '08:00', 
           end: '17:00', 
           dow: [ 1,2,3,4,5 ]
  
           },
           {
           start: '10:00', 
           end: '16:00', 
           dow: [ 6 ]
  
           }]
  </code></pre>
  
  <p>This is not working. The fullcalendar recognizes this array as a true value, and sets the default value of businesHours. </p>
  
  <p>This works: </p>
  
  <pre><code> businessHours:
  
          {
           start: '08:00', 
           end: '17:00', 
           dow: [ 1,2,3,4,5 ]
  
           }
  </code></pre>
  
  <p>But I want to be able to customize every day's opening hours. Is there any way to solve this? If I could add somehow a css class to certain time ranges that would do it, but I don't know how to grab these time ranges. Render doesn't work, because of agenda view.</p>
