schemas/VegCore/VegCore.ERD.mwb: taxon_determination: changed IS-A relationship with taxon_observation to HAS-A so that a separate taxon_observation doesn't need to be created for each taxon_determination (even though each taxon_determination event is theoretically a reobservation of the specimen, etc.). instead, inherit from sampling_event to include the necessary event-related fields.
