bugfix: inputs/*/Source/map.csv: added missing row_num entry, which is needed by the staging table column renaming to make the order of the map.csv columns match the order in the staging table. the staging table column renaming is now used by all Source tables.

added inputs/newWorld/iso_code_gadm/header.csv

added inputs/analytical_db/table.run

bugfix: inputs/VASCAN/Taxon/map.csv: added missing row_num column added by bin/csv2db

lib/sql_io.py: cleanup_table(): added assertion that the table exists, so that if it doesn't, the error will occur as part of an assertion rather than as part of the util.table_nulls_mapped__get() call, which might confusingly lead users to believe that this is a bug in util.table_nulls_mapped__get() when in fact the problem is that the table is not installed

fix: inputs/import.stats.xls: removed spurious diff comment on total time, which only applied to the previous import

inputs/import.stats.xls: reformatted times longer than one day as a # of days instead of hours, for clarity. the days format is chosen automatically when the # hours exceeds one day.

bugfix: inputs/*/Source/: added missing ./run, which creates the new-style staging tables with the metadata fields as part of the table. this is needed now that these subdirs use installed staging tables instead of metadata-only map.csvs.

bin/map: removed no longer used support for map.csv input column prefixes (expand out the prefixes instead). this used to be used by SpeciesLink to use just one mapping for a single term with multiple DwC namespaces, but was replaced with an explicit, ordered rather than implicit, unordered /_alt-ing together of the terms.

bin/map: removed no longer accurate comment that this is case- and punctuation-insensitive, since the case- and punctuation-insensitivity is now instead handled by map.csv preprocessing scripts before the mappings are even provided to bin/map
