lib/sh/util.sh: added $verbosity_min to set a `verbosity_min` value after the command name, etc. has been logged, so that the logging itself is not output with the new verbosity

schemas/vegbien.sql: range_modeling_input: include only plants (i.e. rows with higher_plant_group IS NOT NULL)

schemas/vegbien.sql: range_modeling_input: added higher_plant_group, for use in restricting rows to plants

inputs/.geoscrub/geoscrub_output/map.csv: *validity: added definitions of the numeric codes from _src/README.TXT

added planning/workflow/validation/GeoDistKM.sql.txt

planning/goals/BIEN3_derived_data_products.docx: updated to most recent version from Brad's e-mail on 2013-4-16

/README.TXT: Full database import: before running screen: added `unset TMOUT` because TMOUT (autologout) causes screen to exit even with background processes active

/README.TXT: Maintenance: added things to put in your .profile on a live machine (e.g. vegbiendev). in particular, you MUST NOT have a TMOUT (autologout) set, because this causes screen to exit even if background processes (e.g. from column-based import) are running

bugfix: lib/runscripts/table.run: load_data(): need to ensure the verbosity is at least 3 because the install logs require verbose output. (3 is the default for the installer, but is overridden by the runscripts, which instead set the default to 1.)
