join: Fixed bug where when an input to mapped to multiple outputs, the joined row for each output needed to be output separately using writer.writerow()

sort_map: Remove duplicates resulting from multiple outputs for the same input. mappings/Makefile: $(mkSelfMap): Removed uniq now that sort_map does this.

mappings/Makefile: $(mkSelfMap): Run uniq on the output to remove duplicates resulting from multiple outputs for the same input

expand_braces: Also expand XPaths containing [], with up to one level of nesting (which is the most we currently use), because many {} XPaths do in fact contain []. Debug-print intermediate values when env var expand_braces_debug is true. Added usage message.

expand_braces: Fixed bug where ./{ and brackets with commas inside {} are unparseable, and should not be expanded

expand_braces: Fixed bug where `head -1` seemed to read more lines than just the first, causing EOF to be returned after the first line, by using `read` instead. Support data containing \r (such as Excel-dialect CSVs) by removing it. Fixed bug where ./{...} was not being properly escaped.

Added expand_braces

mappings: location: Removed centerlatitude/centerlongitude mappings because the lat/long should be in only one place: the locationdetermination. It is up to the database querier to decide which locationdetermination(s) to use as the coordinates for a plot/specimen.

bin/map: input is CSV: Removed unused map_ var

bin/map: Documented that it's multi-safe (supports an input appearing multiple times)
