This script provides an example implementation of access to a local
Taxonomy database implemented with Berkeley DB (DB_File module is needed).
bp_local_taxonomydb_query.PLS: [-v] --nodes nodes.dmp --names names.dmp "Genus1 species1" "Genus2 species2"
Providing the nodes.dmp and names.dmp files from the NCBI Taxonomy
dump (see Bio::DB::Taxonomy::flatfile for more info) is only necessary
on the first time running. This will create the local indexes and may
take quite a long time. However once created, these indexes will
allow fast access for species to taxon id OR taxon id to species name
