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/input.Makefile: SVN: add, %/add: */logs: also svn:ignore *.gz, used for compressed log files

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
