C4::Members::AttributeTypes - mananage extended patron attribute types
=head1 SYNOPSIS
my @attribute_types = C4::Members::AttributeTypes::GetAttributeTypes();
my $attr_type = C4::Members::AttributeTypes->new($code, $description);
$attr_type->code($code);
$attr_type->description($description);
$attr_type->repeatable($repeatable);
$attr_type->unique_id($unique_id);
$attr_type->opac_display($opac_display);
$attr_type->password_allowed($password_allowed);
$attr_type->staff_searchable($staff_searchable);
$attr_type->authorised_value_category($authorised_value_category);
$attr_type->store();
$attr_type->delete();
my $attr_type = C4::Members::AttributeTypes->fetch($code);
$attr_type = C4::Members::AttributeTypes->delete($code);
=head1 FUNCTIONS
=head2 GetAttributeTypes
my @attribute_types = C4::Members::AttributeTypes::GetAttributeTypes($all_fields);
Returns an array of hashrefs of each attribute type defined
in the database. The array is sorted by code. Each hashref contains
at least the following fields:
- code
- description
If $all_fields is true, then each hashref also contains the other fields from borrower_attribute_types.

=head2 AttributeTypeExists

Returns true if we have attribute type C<$code>
in the database.

Create a new attribute type.

=head2 fetch
my $attr_type = C4::Members::AttributeTypes->fetch($code);
Fetches an attribute type from the database. If no
type with the given C<$code> exists, returns undef.

Stores attribute type in the database. If the type
previously retrieved from the database via the fetch()
method, the DB representation of the type is replaced.
