*{.sh,run}: runscript targets: use begin_target instead of echo_func so the target name is properly echoed. note that this requires using with_rm so that $rm is properly progagated to applicable invoked targets. (previously, $rm was progagated to all invoked targets. note that with_rm only works inside a runscript target that starts with begin_target.)

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)
