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).

bugfix: exports/2013-10-18.Brian_Enquist.Canadensys.csv.run: do not override the table to analytical_stem, because the extract-specific view should be used instead. this was actually benign, because extract.run export_() always sets $table to the extract-specific view.

exports/2013-10-18.Brian_Enquist.Canadensys.csv.run: documented runtime (35 min, now that bugs have been fixed)

exports/2013-10-18.Brian_Enquist.Canadensys.csv.run: inherit from new import_subset.run (which uses extract.run)

added exports/2013-10-18.Brian_Enquist.Canadensys.csv.run
