schemas/VegBIEN/attribution/: moved into schemas/VegBIEN/planning/

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).

schemas/VegBIEN/attribution/BIEN 3 data use and attribution.docx: changed dataset definition to the definition in normalized VegCore ("a collection of records from the same place, with the same attribution requirements"), following discussion with Ramona

schemas/VegBIEN/attribution/BIEN 3 data use and attribution.docx: updated to Ramona's commented version

schemas/VegBIEN/attribution/BIEN 3 data use and attribution.docx: made Ramona's corrections with track changes turned on. note that you have to use MS Word for this, not LibreOffice, because LibreOffice can't save the table of contents properly in .docx or .doc format (although it can save it in .odt format).
