[jmsl] Insertion index for Track...?

[jmsl at music.columbia.edu]

Hi Nick,

How does EditManager choose where in the track to insert to?  I've  
found methods for finding the nearest note to a clicked point, but  
that is dependent on spacing, and a sparsely spaced measure would not  
work well with this.  Is there a convenience method that I'm missing  
that does this?  (I'm writing my own EditManager)

thanks,
Peter McCulloch
