inputs/import.stats.xls: Updated import times

README.TXT: Data import: Changed `inputs/*/*/logs` to `inputs/{.,}*/*/logs` to also include the TNRS names import log

import_all: Added commands to import TNRS names so the user doesn't have to do this manually

sql.py: map_expr(): Fixed bug where names were being matched inside punctuated names replaced in previous calls of map_expr()

schemas/vegbien.sql: party: party_required_key: Only allow NULL organizationname if party is not a root party (i.e. creator_id != party_id)

mappings/VegCore-VegBIEN.csv: Mapped to new taxonconcept.creationdate

schemas/vegbien.sql: taxonconcept: taxonconcept_required_key: Added creationdate as an allowable minimum field when parent_id (containing the associated hierarchical concept) is specified

schemas/vegbien.sql: taxonconcept: taxonconcept_required_key: Removed family and genus because these are now cached fields only, and are not used for scoping a taxonconcept. Instead, *taxonomicname and taxonname+parent_id are used for this purpose. This removes several leaf taxonconcepts with insufficient scoping information to create a taxonconcept separate from the main tree. With the upcoming population of creationdate, some of these taxonconcepts will reappear due to the date's additional distinguishing information.

schemas/vegbien.sql: taxonconcept: Added creationdate (the date the taxonconcept was created or defined), and include it in the taxonconcept_unique unique index

schemas/vegbien.sql: taxonconcept: Added comment with the definition of a taxon: "a group of one (or more) populations of organism(s), which a taxonomist adjudges to be a unit" (http://en.wikipedia.org/wiki/Taxon). This is useful in clarifying that our taxon concepts are intended to serve a similar purpose, by storing one person's defined taxon.
