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/REMIB/Specimen/create.sql: moved filtering out of frameshifted rows to postprocess.sql, where it can happen in an idempotent DELETE. this allows filters to remove additional rows to easily be added on top of the existing filters, without needing to remake Specimen (which takes a long time, because of the many stage I derived columns that get added). the logical inversion inherent in the DELETE condition has been factored through rather than wrapped in NOT (...), because removal of frameshifted rows is more accurately specified as the detection of specific patterns that indicate frameshifting rather than the validation of all fields.

inputs/REMIB/Specimen/create.sql: also remove frameshifted rows with invalid long_deg values

inputs/REMIB/Specimen/create.sql: Also filter out rows where acronym (collectionCode) is NULL because this is a required field for valid records

inputs/REMIB/Specimen/: Filter out invalid, frameshifted rows so they don't produce errors in the import or anomalies like thousands of taxondeterminations for one taxonoccurrence. This involves moving the CSVs to Specimen.src and using a create.sql to create the filtered table.
