This is similar to what we do with investments, which belong to a heading
but also belong to a budget. In our case, the reason is we've been asked
to add local targets which belong to a goal but are not related to any
existing target.
Even though we're not implementing that case right now, we're adding the
relation so we don't have to add data migrations in the future.
and its relation with relatables
Note about sdg_review factory: Cannot use the constantize method on
the relatable_type as long as the relatable classes will be loaded and
this will throw an exception because the database is not available at
factiry definition time.
and its relation with the SDG goal model.
Add comparable module be able to sort collections of targets
by code attribute.

Since data for this model (title and description) is not generated in
CONSUL but by the United Nations, we aren't storing it in the database
but in our YAML translation files.
The reasoning is as follows. Suppose that, a few months after CONSUL
gets SDG support, a new language is added to CONSUL.
With YAML files, getting the texts in the new language would mean
updating CONSUL to include the new language.
But if we store these texts in the database, it means we have to update
the databases of all existing CONSUL installations, either each
installation by themselves (duplicating efforts) or running a rake task
(which we would have to write each time).
So we believe using translations works better in this case.
We're still storing records in the database with the code, so they can
be easily referenced via `has_many` or `has_many :through` associations.
