mappings/VegCore-VegBIEN.csv: taxonconcepts: Also create the taxonconcept tree if datasource provided separated components of the taxonomic name and/or its own tree of life with higher classifications. This enables storing the datasource's own tree of life to supplement any official tree (TROPICOS, USDA, etc.).

mappings/VegCore-VegBIEN.csv: taxonconcept tree: Don't map infraspecificEpithet+taxonRank to a taxonconcept in the tree of parent concepts because it has already been mapped to the primary, lowest-level taxonconcept

schemas/vegbien.sql: taxonconcept: taxonconcept_unique_within_creator_by_name unique index: Fixed bug where index filter overlapped with taxonconcept_unique_within_parent's index filter, causing these unique indexes to sometimes both apply at the same time and prevent column-based import from correctly choosing which index to use for each taxonconcept import

schemas/vegbien.ERD.mwb: Fixed lines

schemas/vegbien.sql: taxonconcept.canon_taxonconcept_id comment: Changed comment to use "concept" rather than "name" where applicable. Documented that a synonym between taxonconcepts of different sources is indicated by choosing one taxonconcept to be authoritative and pointing the other taxonconcept to it using this field.

sql_io.py: put_table(): Resolving default value column: Fixed bug where the default value col needed to have its table changed from in_table to full_in_table if it's a table column, and needed to have any column rename removed if it's a literal value

Regenerated vegbien.ERD exports

schemas/vegbien.sql: Renamed plant* taxonomic tables -> taxon*, as part of the taxonomic schema refactoring at <https://projects.nceas.ucsb.edu/nceas/projects/bien/wiki/2012-10-03_conference_call#Taxonomic-schema-refactoring>

schemas/vegbien.ERD.mwb: Rearranged to fit more of location table on the diagram, using the newly available space from taxon
