schemas/vegbien.sql: taxonconcept: Removed no longer used higher- and infraspecific taxonomic rank fields because these terms are now stored in their own taxonconcepts. family, genus, and species have not been removed because these are used to cache names of parent taxa for fast access by analytical_db_view.

schemas/vegbien.sql: analytical_db_view: Changed taxonMorphospecies to use taxonconcept.taxonname, where any morphospecies is now stored

mappings/VegCore-VegBIEN.csv: infraspecific taxonomic terms: Removed mappings to first-class taxonconcept fields because these terms are now stored in their own taxonconcepts, or in the lowest-level taxonconcept as the taxonname and rank

mappings/VegCore-VegBIEN.csv: higher-level taxonomic terms: Removed mappings to first-class taxonconcept fields because these terms are now stored in their own taxonconcepts

schemas/vegbien.sql: taxonconcept: Merged taxonconcept_unique_within_creator_by_name unique index into taxonconcept_unique_within_parent, placed parent_id first, and removed index condition, so that this index can be used as a lookup index by taxonconcept_update_ancestors() (which requires no index condition in order to apply to all taxonconcepts) in addition to as a unique index. Note that an index condition should not be necessary for the index's uniquifying task, because if a set of taxonconcepts provides only the identifyingtaxonomicname, that should collide in the taxonconcept_unique_within_creator_by_identifying_name unique index before this index collides. This assumes that the collision order when multiple indexes collide is alphabetical by the index name.

schemas/vegbien.sql: taxonconcept: taxonconcept_required_key check constraint: Also allow a taxonconcept to have just an author when it has a parent_id, so that an author can uniquely identify a taxon within a more general taxon, such as a species name, that has no author

strings.py: concat(): Fixed bug where end index of returned str0 portion would wrap around to a negative number if str1 itself was too long, causing incorrect truncation

schemas/vegbien.sql: taxonconcept: Renamed taxonconcept_unique_within_parent to taxonconcept_unique because the index does not apply only to taxonconcepts with a parent, and because it's the primary unique index for taxonconcept

schemas/vegbien.sql: taxonconcept: Renamed taxonconcept_unique_within_creator_by_identifying_name to taxonconcept_0_unique_identifying_name to ensure that it is always applied before taxonconcept_unique_within_parent if both collide

schemas/vegbien.sql: taxonconcept: Merged taxonconcept_unique_within_creator_by_name unique index into taxonconcept_unique_within_parent, placed parent_id first, and removed index condition, so that this index can be used as a lookup index by taxonconcept_update_ancestors() (which requires no index condition in order to apply to all taxonconcepts) in addition to as a unique index.
