Bug fix

  - Bug fix for #3 (h/t @ekatef), in which columns with uppercase names
    were dropped by default due to internal conflict with case_ignore
    and drop_extra options.

                 Changes in version 0.2.3 (2019-02-25)                  

Bug fix

  - Bug fix for issue #2 due to update of labelled package to 2.1.0

                 Changes in version 0.2.2 (2018-11-26)                  

  - 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.
  - new tests
