moved everything into /trunk/ to create the standard svn layout, for use with tools that require this (eg. git-svn). IMPORTANT: do NOT do an `svn up`. instead, re-use your working copy's existing files with `svn switch` (http://svnbook.red-bean.com/en/1.6/svn.ref.svn.c.switch.html).
bugfix: mappings/VegCore-VegBIEN.csv: nest all taxonoccurrences inside a stratum event, so that the parent locationevent is always fully populated before child locationevents point to it. (previously, a stub parent event was created when the child event was imported first, which blocked the fully-populated parent event from being inserted later on.) this uses auto-folding (for VegBank/CVS) and auto-forwarding (for other datasources) to prune empty stratum events for taxonoccurrences that don't have strata. (see wiki.vegpath.org/Auto-folding, wiki.vegpath.org/Auto-forwarding for more info about these normalization techniques.) note that the inserted row counts stay exactly the same for all datasources except VegBank (which was being fixed), indicating that this signficant change to the mappings did not change the semantics of the import of taxonoccurrences.
inputs/*/*/map.csv for CSV tables with a row_num column: added missing row_num entry, which is needed by the staging table column renaming to make the order of the map.csv columns match the order in the staging table
mappings/VegCore-VegBIEN.csv: subplotID,subplot -> location.sourceaccessioncode: Fixed bug where need /_first to handle the case where both subplotID and subplot are provided
inputs/NVS/Plot/map.csv: Corrected Plot ID mapping to go to subplotID instead of locationID, because each subplot gets its own ID in this field
mappings/VegCore-VegBIEN.csv: locationID/locationName + subplot -> location.sourceaccessioncode mapping: Fixed bug where subplot was incorrectly being mapped to this field even when there was no location*. (This field can only be populated if both location* and subplot are specified.) Also only map locationID for this, to avoid inconsistencies where one table supplies locationID+subplot, while another table supplies locationName+subplot, but they both get mapped to the same field, preventing plots from being matched up with their observations when creating the analytical_stem.
mappings/VegCore-VegBIEN.csv: authortaxoncode mappings: Only use authorTaxonCode if there is no plant ID, because an individual plant gets its own taxonoccurrence and thus needs the taxonoccurrence's IDs to be unique to the plant, regardless of what the author designates as the taxonoccurrence code
mappings/VegCore-VegBIEN.csv: Mapped authorTaxonCode
inputs/NVS/Plot/map.csv: Mapped Plot
inputs/NVS/Plot/map.csv: Mapped Physiography
inputs/NVS/Plot/map.csv: Mapped Area
inputs/NVS/Plot/map.csv: Altitude: Provided rationale for units determination
