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 planning/workflow/derived_columns/range_measurements/low-high_vs_midpoint-uncertainty.VegBank.png diagram, generated from a screenshot of the VegBank Data Dictionary (VegBank.vegpath.org/plot#Elevation)

removed planning/workflow/bien3_architecture.odp because the current version is now in bien3_architecture.pptx

added planning/workflow/validation/TNRS_results.ppt symlink to inputs/test_taxonomic_names/_scrub/TNRS_results.ppt

planning/workflow/bien3_architecture.pptx: exported from bien3_architecture.odp, as requested by Martha. the .pptx format is buggy and doesn't show the slide thumbnails on the slide notes view, but will have to do as .ppt (the older MS PowerPoint format) doesn't support the graphics.

planning/workflow/bien3_architecture.odp: added wiki page notes (wiki.vegpath.org/2013-06-20_conference_call, wiki.vegpath.org/2013-06-27_conference_call) in the slide notes

planning/workflow/bien3_architecture.odp: added responses to the red-highlighted questions (from e-mails to the list) in the slide notes

added planning/workflow/bien3_architecture.odp with changes from Skype call with Martha, which include wiki page notes (wiki.vegpath.org/2013-06-20_conference_call) about the refactor-in-place method in the Notes area

planning/workflow/bien3_architecture.pptx: updated to Martha's revised version from 2013-7-3

planning/workflow/validation/: archived BIEN2 validations documents which have been superseded by planning/goals/BIEN3_derived_data_products.docx, to avoid confusion
