mappings/VegCore.htm: Regenerated from wiki. Brad's new DwC ID terms spreadsheet has now been added, and a number of the ID terms clarified, disambiguated, and recategorized. In particular, institutionCode has now been split into the custodialInstitutions and collectingInstitution, to differentiate between which institution has the specimen vs. stamped the specimen. This distinction is important because the catalogNumber, stamped on the specimen, is only unique within the collectingInstitution. Most datasources don't unambiguously specify which institution their institutionCode is referring to, so it has been assumed to be custodialInstitutions unless a data dictionary says otherwise (as is the case for UNCC). In addition, a MatchedTaxonDetermination table has been added with the *_matched fields from TNRS.
