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: inputs/ARIZ/~.clean_up.sql: prevent "column already exists" errors when there is an input column of the same name as an output column

**/new_terms.csv, unmapped_terms.csv updated (using `make missing_mappings`)

copyright scrub: inputs/: removed data provider-owned schema and documentation files, which are not BIEN copyright and should not be part of what is submitted for open-sourcing. these files will remain accessible via the web interface (fs.vegpath.org), but will not be in the repository.

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

fix: inputs/ARIZ/omoccurrences/map.csv: occurrenceID: remapped to EQUIV#to:occid instead of DUPLICATE#of:occid since these are not exact duplicates

inputs/*/Specimen/test.xml.ref with eventDate->dateCollected mappings: updated test outputs to match mapping

bugfix: inputs/ARIZ/omoccurrences/map.csv: fixed one-to-many mapping for modified (created by the automapper?)
