inputs/VegBank/stemlocation_/test.xml.ref: updated

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).

inputs/VegBank/stemlocation_/header.csv: updated from reinstalling stemlocation_

fix: bin/map: put template: comment out the "Put template:" label so that the output is valid XML, and displays properly in a browser rather than showing a syntax error

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//: don't import joined tables, because they are now imported in the taxon_observation.** left-join instead

bugfix: inputs/VegBank/stemlocation_/map.csv: remapped stemcount-related fields to OMIT, so that these don't collide with fields of the same name in stemcount_ when they are left-joined together in taxon_observation.** . having the same name causes these to be incorrectly interpreted as shared fkey columns in the NATURAL JOIN (and without the NATURAL JOIN, they would instead be collision errors).

bugfix: inputs/VegBank/stemlocation_/postprocess.sql: added missing index on aggregateOrganismObservationID, needed for the 1:many portion of the taxon_observation.** left-join

inputs/VegBank/: prepended the table name to each column name to prevent column collisions, using the steps at http://wiki.vegpath.org/Left-joining_a_datasource

inputs/VegBank/: switched to new-style import, using the steps at http://wiki.vegpath.org/Adding_new-style_import_to_a_datasource
