C4::Members::Messaging - manage patron messaging preferences
=head1 SYNOPSIS
use C4::Members::Messaging
=head1 DESCRIPTION
This module lets you modify a patron's messaging preferences.
=head1 FUNCTIONS
=head2 GetMessagingPreferences
my $preferences = C4::Members::Messaging::GetMessagingPreferences( { borrowernumber => $borrower->{'borrowernumber'},
message_name => 'Item_Due ' } );
my $preferences = C4::Members::Messaging::GetMessagingPreferences( { categorycode => 'LIBRARY',
message_name => 'Item_Due ' } );
returns: a hashref of messaging preferences for a borrower or patron category for a particlar message_name
Requires either a borrowernumber or a categorycode key, but not both.
message_name argument is a message attribute name.

=head2 SetMessagingPreference
This method defines how a user (or a default for a patron category) wants to get a certain
message delivered. The list of valid message types can be delivered can be found in the
C<message_attributes> table, and the list of valid message transports can be
found in the C<message_transport_types> table.
C4::Members::Messaging::SetMessagingPreference( { borrowernumber => $borrower->{'borrowernumber'}
message_attribute_id => $message_attribute_id,
message_transport_types => [ qw( email sms ) ],
days_in_advance => 5
wants_digest => 1 } )
returns nothing useful.
