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: bin/*: spell out [:alnum:] as [a-zA-Z0-9] because Python unfortunately doesn't support character classes
bin/*: replaced confusing regexp constructs involving \W inside [] with the much clearer explicit character class [:alnum:] . this avoids adding or subtracting from an inverted class in order to reach a subset of the corresponding positive class, because the subset can just be named explicitly instead.
bin/filter_out_ci, lib/maps.py: simplify(): also remove distinguishing #... suffix from terms (e.g. UNUSED#institutionID), to support mapping multiple columns to the special terms OMIT, PRIVATE, UNUSED (VegCore.vegpath.org#Special-terms), without creating a collision in the staging table renaming. note that this change must not be made to bin/canon, because this would cause suffixed terms to be autorenamed to their *un*suffixed VegCore versions.
filter_out_ci: Filter header instead of passing it through, in order to properly support CSVs without a header, such as the unmapped_terms.csv and new_terms.csv files. For CSVs with a header, the header of the vocabulary should be removed before passing it to filter_out_ci.
canon, translate, filter_out_ci: Support vocabularies/dictionaries with additional columns in addition to the functional column(s) used by the program. These columns can contain comments, etc. This was not originally supported because Python 2's iterable unpacking only supports "an iterable with the same number of items as there are targets in the target list" (http://docs.python.org/reference/simple_stmts.html#assignment-statements). We now use numeric array indexes instead to get around this limitation, and for consistency with other map-manipulation scripts.
Added filter_out_ci
