=head1 NAME

SL::CVar.pm - Custom Variables module

=head1 SYNOPSIS

# dealing with configs

my $all_configs = CVar->get_configs()
my $config = CVar->get_config(id => '1234')

CVar->save_config($config);
CVar->delete->config($config)

# 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 cofigured. 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)
