mappings/VegX-VegBIEN.stems.csv: Expanded {} expressions using expand_braces, so that each distinct output for the same input is on its own line, improving readability. This will also help enable search-and-replace reversing of XPaths for the re-rooting to location.

mappings/VegX-VegBIEN.stems.csv: VegX XPaths: Expanded {} expressions using expand_braces, so that later use of expand_braces on the file would not affect the VegX output mappings of the inputs' via maps (VegX.organisms.csv, etc.)

mappings/DwC2-VegBIEN.specimens.csv: Expanded {} expressions using expand_braces, so that each distinct output for the same input is on its own line, improving readability. This will also help enable search-and-replace reversing of XPaths for the re-rooting to location.

README.TXT: Accepting test cases: Documented that when refactoring mappings, it's helpful to use WinMerge to detect moved lines

expand_braces: Fixed bug where needed to get next line from stdin in raw mode, so that \ won't be parsed as escape chars

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
