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).

copyright scrub: inputs/: removed data provider-owned schema and documentation files, which are not BIEN copyright and should not be part of what is submitted for open-sourcing. these files will remain accessible via the web interface (fs.vegpath.org), but will not be in the repository.

inputs/FIA/: archived no longer used BIEN2 FIA data from the nimoy geoscrub DB

inputs/FIA/: Added FIA_COND table from nimoy.geoscrub and code to generate a unique plot table from it, including the oldgrowth calculated field
