sets the 'cascade' display mode
scheduler.config.cascade_event_display = true;
scheduler.config.cascade_event_count = 4;
scheduler.config.cascade_event_margin = 30;
...
scheduler.init('scheduler_here',new Date(2009,5,30),"week");
By default, events scheduled to the same time are displayed one by one. If you want to present such events as a cascade, set the option to true.
