fix: inputs/.geoscrub/geoscrub_output/postprocess.sql: map_geovalidity(): unscrubbable names should actually be geo*in*valid, not geovalid=NULL, according to Brad

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/.geoscrub/geoscrub_output/postprocess.sql: added nullable unique index on the inputs, for use by analytical_stem_view. note that it must be nullable in order to create a match when not all of the input fields are populated. this uses array[] to create a nullable index, which is much better than column-based import and VegBIEN's use of COALESCE because the expression is the same for every type and no NULL sentinel value is needed.

inputs/.geoscrub/geoscrub_output/postprocess.sql: added geovalid derived column, for use by analytical_stem_view

inputs/.geoscrub/geoscrub_output/postprocess.sql, run: updated runtimes

inputs/.geoscrub/geoscrub_output/postprocess.sql: updated runtimes for refreshed data, which now has 4x as many rows (1,707,970->6,747,650)

inputs/.geoscrub/: switched to new-style import, using the steps at wiki.vegpath.org/Adding_new-style_import_to_a_datasource

inputs/.geoscrub/geoscrub_output/: translated single-column filters to postprocessing derived columns, using the steps at wiki.vegpath.org/Adding_new-style_import_to_a_datasource#Translating-filters-to-postprocessing-derived-columns

inputs/.geoscrub/geoscrub_output/postprocess.sql: set decimallatitude, decimallongitude types to double precision to facilitate joining with other double precision values

inputs/.geoscrub/geoscrub_output/postprocess.sql: coords index: added rest of input columns so this can be used to check the existence of a result by input. added runtime (55 s). use idempotent create_if_not_exists().

inputs/.geoscrub/geoscrub_output/postprocess.sql: Added index on decimallatitude, decimallongitude

Added inputs/.geoscrub/geoscrub_output/postprocess.sql, which adds NOT NULL constraints on decimallatitude, decimallongitude
