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).
inputs/: Renamed subfolders to VegCSV names, using the steps at <https://projects.nceas.ucsb.edu/nceas/projects/bien/wiki/VegCSV_subfolders#Rename-subfolders-to-VegCSV-names>
inputs: Move src subdir into main dir, using the steps at <https://projects.nceas.ucsb.edu/nceas/projects/bien/wiki/VegCSV_subfolders#Move-src-subdir-into-main-dir>
inputs: Moved maps into subfolders, using the steps at <https://projects.nceas.ucsb.edu/nceas/projects/bien/wiki/VegCSV_subfolders#Move-maps-into-subfolders>
inputs: Replaced Veg+ prefix with map on via maps, using the steps at <https://projects.nceas.ucsb.edu/nceas/projects/bien/wiki/VegCSV_subfolders#Replace-Veg-prefix-with-map-on-via-maps>
Merged DwC (including DwC1) and VegCSV mappings into new Veg+ schema. This involves replacing occurrences of DwC and VegCSV with Veg+ (or sometimes VegCore) everywhere, as described in <https://projects.nceas.ucsb.edu/nceas/projects/bien/wiki/VegCSV-DwC_merging>.
input.Makefile: Clean up via maps when they change by subtracting the via format's self map from the via map (the comments column is ignored in determining which entries are redundant, and empty entries with a matching input column are also removed)
