First changes to include Bio2RDF based dbxref mappings.
Added 2-col TSV-to-Ruby static class converter. Pseudo Bio2RDF abbreviation dictionary added (for testing). Genomics output makes use of this new Bio2RDF dictionary.
Database abbreviation is part of the Life Science Registry (not Bio2RDF). Renamed file accordingly.
Changed previous wrong naming of Bio2RDF to Life Science Registry.
Life Science Registry as of 11th March 2014.
Uses Life Science Registry to write out Dbxrefs (direct mentions only, for now).
