added schemas/VegCore/Brad_Boyle/bien3_data_provenance_use_cases.docx* from e-mail from Brad
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).
added schemas/VegCore/Brad_Boyle/BIEN 3 data use and attribution.docx symlink to schemas/VegBIEN/attribution/BIEN 3 data use and attribution.docx, so that all of Brad's attribution-related terms are in one place
Added schemas/VegCore/Brad_Boyle/ with Brad's VegCore IDs terms spreadsheets
