title: fullcalendar, how to limit the number of events per day in the month view
body: <p>I have many events on a day, and it works as expected but now looking at the month view, my calendar grid is much taller that expected.  I'd like to hide some of these events from the month view, like a summary with a visual que that there are more on this day than can be shown.</p>
  
  <p>I can use eventRender and return false, but i would like to know how many events are on a given day, so i can limit the rendering to about 4, then perhaps i would add an event that says " more ... "</p>
  
  <p>So the question may be : how to count the events on a given date ?</p>
  
  <p>or is this more like a feature request to expose a max counter for month view ?</p>
  
  <p>thanks</p>
