dwctaxon 2.0.3

Bug fixes

• Don't require that all values of a reference column be unique when matching
  values, instead only require that the matched values be unique. This means
  it is now possible to use (for example) dct_fill_col() to fill
  acceptedNameUsageID based on scientificName even if scientificName
  contains some duplicated values, as long as those don't match any
  values in the match_from column
  (#97)

Documentation

• Add documentation of extra_cols option in dct_options() (#99)

CRAN policies

• Add a check for an internet connection and valid URL when downloading files to
  ensure compliance with CRAN policy (#94)
