activates/disables checking of limits
scheduler.config.check_limits = false; ... scheduler.init('scheduler_here',new Date(2013,7,6),"week");
The parameter is available from version 3.5.
It makes sense to disable this option when you don't set any limits and just make some highlighting or mark the current time - this will increase the performance speed. But if you have some limitation set, disabling this option will disable all the 'blocking' methods
