> Doc values fields are single-valued by design, ie a given field name can only occur once
in the document.
> But if you accidentally add it more than once, you get an assert error, which is spooky
because if you run w/o asserts maybe something eviler happens.
> I think we should explicitly check for this and throw clear exc since user could easily
do this by accident.
