Wanted to get this out before refactoring. Still have a pending question regarding unloaded annual data and whether we should be handling that better.
Oh ok. Sorry, I just saw your comment:

That makes sense! Kudos for figuring out how to get that out of the TimeSeries* classes. I wish I had documented them better. I should usejsdoc.org more consistently.
