=head1 NAME

App::CELL::Message - handle messages the user might see



=head1 SYNOPSIS

    use App::CELL::Message;

    # server messages: pass message code only, message text
    # will be localized to the site default language, if 
    # assertainable, or, failing that, in English
    my $message = App::CELL::Message->new( code => 'FOOBAR' )
    # and then we pass $message as an argument to 
    # App::CELL::Status->new

    # client messages: pass message code and session id,
    # message text will be localized according to the user's language
    # preference setting
    my $message = App::CELL::Message->new( code => 'BARBAZ',
                                          session => $s_obj );
    $msg_to_display = $message->App::CELL::Message->text;

    # a message may call for one or more arguments. If so,
    # include an 'args' hash element in the call to 'new':
    args => [ 'FOO', 'BAR' ]
    # they will be included in the message text via a call to 
    # sprintf
