[jmsl] startTime or scheduling MusicShape start

[jmsl at music.columbia.edu]

Well, I found kind of an odd, but perfectly functional, was around  
this... Just using a ParallelCollection instead of a  
SequentialCollection, and setting the startDelay of each MusicShape to  
the desired absolute start time.
Perfect! (I built this into my mock Player class, as well, and it  
works just as expected.)
I see that I could also use EventScheduler, but I'll stick with this  
ParallelCollection approach, for now - I like the fact that it gives  
me a specific data structure for storing and scheduling MusicShapes.  
Also, from what I understand, I can still add these  
ParallelCollections to another ParallelCollection, to get the function  
of a sort of "multi-track" sequencer.
Just what I need, at the moment!

cheers,

J.
