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).

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

inputs/*/ which do not contain any explicit collisions (wiki.vegpath.org/2013-06-27_conference_call#To-do-for-Aaron > #3.2 > the following datasources ...): switched to new-style import, which adds the staging table column renaming

inputs/*/*/map.csv: added distinguishing #... suffix (e.g. UNUSED#institutionID) to the special terms OMIT, PRIVATE, UNUSED (VegCore.vegpath.org#Special-terms) to avoid creating a collision in the staging table renaming

inputs/*/Source/VegBIEN.csv: regenerated for new-style import, which uses a symlink to mappings/VegCore-VegBIEN.csv instead of a custom mapping using the original column names

inputs/bien2_traits/TraitObservation/map.csv: removed no longer needed mappings of dummy columns to OMIT, which were creating an unnecessary collision of staging table column names

inputs/bien2_traits/bien2_staging.schema.sql: regenerated from MySQL version so that dummy columns (which used to be generated by bin/my2pg) will be replaced with dummy CHECK constraints instead. this avoids needing to map several dummy columns all to OMIT, which was creating an unnecessary collision of staging table column names.
