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).
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.pptx: updated to Martha's revised version from 2013-7-3
planning/workflow/bien3_architecture.pptx: updated with clarifications made in today's conference call
planning/workflow/bien3_architecture.pptx: stage II: removed Step prefix before stage #, which the other slides don't have
