encoded vector now output in same class as clean values from crosswalk file; this means that if the raw variable is a character (like state name) and the clean encoding value is an integer (like FIPS code), then the new labelled vector will be an integer class. This is the logical behavior and should work better with transfer to Stata, which only takes labels on numeric classes.
