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

inputs/test_taxonomic_names/test_scrub: Remove any previous version of public.test_taxonomic_names before renaming public to it

inputs/test_taxonomic_names/test_scrub: Fixed bug where public.sql export did not include the "CREATE SCHEMA public" statement, because pg_dump doesn't add it to backups, by using new schemas/rename/% make target to first rename the public schema and then exporting it

root Makefile: VegBIEN DB: Schemas: schemas/rotate: Use new schemas/rename/%

root Makefile: VegBIEN DB: Schemas: Added schemas/rename/% to rename the public schema

mappings/VegCore-VegBIEN.csv: Removed filter preventing taxonomicStatus from being placed in taxonlabel if a morphospecies was provided, because the morphospecies actually never goes in the matched taxonlabel, only the verbatim taxonlabel

mappings/VegCore-VegBIEN.csv: morphospecies: Also place it in the verbatim (input name's) taxonlabel. Note that it does not go in the matched name's taxonlabel, because that contains only fields from the matched name. The verbatim taxonlabel is thus a synonym of the matched taxonlabel where there is no morphospecies, or a child of it if there is a morphospecies.
