my $all_configs = CVar->get_configs()

# dealing with custom vars

CVar->get_custom_variables(module => 'ic')

=head2 VALIDITY

Suppose the following scenario:

You have a lot of parts in your database, and a set of properties configured. Now not every part has every of these properties, some combinations will just make no sense. In order to clean up your inputs a bit, you want to mark certain combinations as invalid, blocking them from modification and possibly display.

Validity is assumed. If you modify validity, you actually save B<invalidity>.
Invalidity is saved as a function of config_id, and the trans_id

In the naive way, disable an attribute for a specific id (simple)
