=head1 NAME

SL::GL - some useful GL functions

=head1 FUNCTIONS

=over 4

=item C<get_active_taxes_for_chart> $transdate $tax_id

Returns a list of valid taxes for a certain chart.

If the optional param transdate exists one entry in the returning list
may get the attribute C<is_default> for this specific tax-dependent date.
The possible entries are filtered by the charttype of the tax, i.e. only taxes
whose chart_categories match the category of the chart will be shown.

In the case of existing records, e.g. when opening an old ar record, due to
changes in the configurations the desired tax might not be available in the
dropdown anymore. If we are loading an old record and know its tax_id (from
acc_trans), we can pass $tax_id as the third parameter and be sure that the
original tax always appears in the dropdown.

The functions returns an array which may be used for building dropdowns in ar/ap/gl code.
