no longer using findLayer, because it does not work to correlate between response layers and map layers by mapping title to name (since the name of the map's layer doesn't update when the user renames -- which I think is a bug).  Instead, you have to use the internal ID.  I'm doing this with a grep statement instead of a utility function.  Hopefully, this is a solution that will hold!  BTW, this fixes https://github.com/leebock/shortlist/issues/14
