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).
fix: inputs/CVS/observation_community/create.sql: communityName: populate from commConcept.commName instead, because commInterpretation.commname is not always populated. this requires left-joining to commConcept.
inputs/CVS/observation_community/map.csv: updated output column names to new input column names, to avoid later output column collisions
inputs/CVS/observation_community/header.csv, map.csv: updated input column names for cvs.~.clean_up.sql renamings
added inputs/CVS/observation_community/, as for VegBank
