[JW Lua] Last tuplet entry not found...

[Robert Patterson]

Based on a test case from Simon, It appears as though Finale creates bogus
tuplet start records for grace notes that coincide with the start of a
tuplet. Semantically you might be able to argue that it isn't a bug, but
effectively the grace notes are in the way and need to be skipped. (Note
that when your loop finally reaches the first non-grace-note entry, it
correctly finds the final entry of the tuplet.)

My recommendation is to simply skip grace notes, since it appears (with
experimentation) that tuplets don't appear on them anyway, even when they
are there in the data. In addition, you might consider skipping any entry
where CalcLastTupletEntry returns nil. (But see the next paragraph.)

An actual unarguable bug I found is that this function fails to correctly
identify the end entries for non-grace-note tuplets where the "in the time
of" value is 0. This is a Finale bug. You might be thinking, "When would I
ever set in-the time-of to 0?" The answer is that my Beam Over Barlines
plugin does it to create beams on standalone note values. However, this
limitation doesn't seem like it's worth working around in RGP Lua. If you
must support it, I suppose you could add Lua code to do so.
