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).
Moved web/BIEN2, IH into aggregators/
Renamed www/ back to web/
web/: Moved auxiliary files into the main/ subdir in preparation for having just the web/ dir. Renamed web/ to www/ so it can be replaced with web/main/.
web/main/IH/: Added lowercase alias
