simple mathematical operations between items in survey flow

[benjamin-manning]

It would be very nice if we could do simple mathematical operations when piping answers between survey questions. Take the following picture:

What we really want, is if the base answer was 17, be able to pipe through "between 16 and 18" instead of "between 17-1 and 17-2"

This should work for +-/*. might have a checking thing to make sure it only gets used when the piped question is numeric.

@benjamin-manning Was thinking about this reading your survey but it feels uncommonly needed? A way you can do this now is run the first survey, manipulate responses however you want and store them as scenarios for the follow-on survey (where you use scenarios instead of piping).

@rbyh I subjectively disagree (but not super strongly). I predict that as more people use edsl, a nontrivial number would want to do this. It's a very simple action. But of course, you probably have a better view of what people do or don't want.

I think we can do this somewhat easily - let me think about it.
