Title: Refdata derived models

I wrote the queries needed to populate the reference data tables, leaving out those tables that will be populated through the admin. I also added a manager class that provides get_or_create methods to call those queries.
I chose to group the derived models classes (ie our own ORM) to a separate module (derived); not sure it's the best thing to do but it made sense to me, let discuss about it.
