So I rewrote my interpolation function to take in input as a numeric array
that can be either in Option Base 0 or 1. It is a Variant. Is there some
way I can tell if this input is a range instead of numeric? Then I can
convert it to values and make this new function also handle the argument
that the exisiting function takes. And so replace it.
