Function definition: (Copy & paste into FileMaker's Edit Custom Function window)
Returns list of items from listB where cfMatch result is 1 for corresponding value of ListA
If ListB is empty then items from ListA are returned where cfMatch result is 1
If getN is 1 (or greater) then instead of returning the matching item, its position in the list is returned.
ListB can be empty; but otherwise an error is returned if valueCount ListB < valueCount ListA.
Dependent on custom function cfMatch
