with_all: Support additional command-line args for the make target, such as vars

sql_io.py: append_csv(): Check that the CSV's header matches the table's columns

schemas/vegbien.sql: Added tnrs table to hold contents of TNRS response

input.Makefile: Existing maps discovery: $(anyMap): Inlined patterns used because they are only used here

schemas/vegbien.sql: taxonpath_canon_taxonpath_id_self_ref(), placepath_canon_placepath_id_self_ref(): Fixed bug where the pkey could only be prepopulated if it was not already set, in order to support UPDATE as well as INSERT statements

schemas/vegbien.sql: taxonpath.canon_taxonpath_id, placepath.canon_placepath_id: Fixed comment describing that the special value 0 creates an automatic self-reference

schemas/vegbien.sql: taxonpath.canon_taxonpath_id, placepath.canon_placepath_id: Added trigger to automatically create a self-reference (indicating a scrubbed name) when set to the special value 0

input.Makefile: Staging tables installation: `%/install: %/create.sql`: Don't add a row number column to the created table because it is now added automatically to the temp table by column-based import (row-based import now also does not require a pkey for DB inputs)

bin/map, db_xml.put_table() (row-based and column-based import): Don't sort the input table by its pkey, in order to support input tables with no pkey. Note that reading the input table in table order and having this match the input flat file's order is only possible with sql_io.import_csv()'s truncation of the table on a failed import, which ensures that the rows will be stored in inserted order.

input.Makefile: Staging tables installation: Removed no longer used $(isJoinedTable). Note that it is no longer necessary for joined tables to be suffixed with ".src" to prevent the creation of a row_num column, which collided during joins.
