tnrs.py: submission_request_template: Use just Tropicos as the name source, as Brad says "GCC is for only one family (Asteraceae)" and USDA's "taxonomy is of lower quality and sometimes conflicts with Tropicos"

sql.py: parse_exception(): function MissingCastException: Support functions with named parameters

sql.py: parse_exception(): function MissingCastException: Support function names enclosed in quotes on the context line

mappings/VegCore-VegBIEN.csv: taxonName: Place it in taxonomicname instead of taxonepithet for lower taxa, because the only datasource that currently provides this field (NCBI) actually provides the full taxonomicname instead of the epithet at the current rank for lower taxa. (taxonomicname is not applicable to higher taxa because their names are not guaranteed to be globally unique.) taxonName may need to be renamed and/or redefined to account for this ambiguity in NCBI's usage.

mappings/VegCore-VegBIEN.csv: Do not include the taxonName in the concatenated taxonomicname because it is NOT globally unique. The same name may be used at different taxonomic ranks and mean different things, and lower taxa may have the name appear in multiple genuses or species, meaning different things.

schemas/vegbien.sql: Added _is_higher_taxon()

README.TXT: Documentation: To import and scrub just the test taxonomic names: Added `make inputs/.TNRS/cleanup` after `make backups/TNRS.backup/restore` because the PostgreSQL collation may differ between vegbiendev's and the user's DB

sql.py: parse_exception(): DoesNotExistException: If item not found was a function and not found only because of a missing cast, raise MissingCastException instead. This should allow automatic casts to be added on function parameters as well as table columns.

schemas/vegbien.sql: analytical_db_view: Fixed bug where needed to join to taxonverbatim on taxonverbatim_id (the pkey) instead of taxonlabel_id, which used to be the pkey but is now an fkey
