`addPopupIframes()` unexported status?

[asadow]

I found addPopupIframes() through #20. I was curious whether it is still being developed for export?

While using it, I noticed a few things:

• A warning would be nice to have if the object supplied to source is less (or greater?) than the length of the data referenced in the group. It causes some unexpected behaviour.
• It's missing the ... arg, which allows for position.

Good points, let me see what I can do
