bugfix: mappings/VegCore-VegBIEN.csv: prefixed taxonomic ranks: use _concat_nullify() so that the prefix is only added if the epithet is non-NULL
mappings/VegCore-VegBIEN.csv: mapped subspecies to new taxonverbatim.subspecies for easier access by validations queries
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).
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/*/*/test.xml.ref: updated source.shortname for new datasource name, which now starts out with .new suffix
added inputs/FIA/*/{VegBIEN.csv,test.xml.ref}, which are now generated by the mapping process for the joined-together tables (even though they are not used by the import, because only occurrence_all is imported)
