Currently the scheduler 'snap' option does not actually snap to the nearest time slot, rather it adjusts the start time +/- the 'majorTick` amount of an event.  So an event scheduled at 8:03 am would snap to 7:33 am or 8:33 am, given a 30 minute 'majorTick'.

I would be helpful to have another option that allows the event to actually snap to the nearest time slot.  So that same 8:03am would snap to 8:00am, 7:30am, or 8:30am.
