I've noticed that in the scheduling methods of the Schedule class that intervals and times can be doubles. Is this still integral time with some divisor? Is there some fixed timestep or can one schedule at any time? Is there a performance hit if some intervals are not repeatable (i.e. irrational)? So I guess what I'm really asking is if time is still discrete and steppables are lumped into bins or if the schedule is truly asynchronous now. I know for a long time MASON had only discrete timesteps.
