This tool allows you to associate
labels and other texts to a list of labels (ex: A ORF gene list).
It keeps the order and associate description
from a flat database you provide.
Tipical use results from an array experiement analysis,
when you got a list of ORF genes ordered by some relevance. You
then want to associate quickly the rest of your database information
to each ORF gene code, like function, name, etc.
