Named fixtures have been introduced with rails 2, but writting all of them by hand is not helpful.
This exporter will :
- read each entries in database for a model and search for a name or title column
- read existing fixtures to get the name
- write each entries for a model using old fixture name, or name/title column or class name and id
- build belongs_to and has_and_belongs_to_many relations using fixture name
