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/.NCBI/nodes/header.csv: Updated for new staging table format, which includes a row_num column in each joined table
inputs/.NCBI/: Renamed higher_taxa to nodes because it currently doesn't just contain the higher taxa
Added inputs/.NCBI/. This uses many of the new schema and mappings features, such as taxonconcept.sourceaccessioncode and parentTaxonID
