=head1 SYNOPSIS

=head1 METHODS

=head2 applist

Returns an array of Net::DNS::APL::ApItem objects.

Each ApItem objecst contains the following attribute that can be
accessed and set using methods of the same name: addressfamily, 
prefix, negation, address

  foreach my $ap ($apl->aplist()){
     	print $ap->negation()?"!":"";		
    	print $ap->addressfamily().":";		
    	print $ap->address();		
    	print $ap->prefix(). " ";
    }

In addition the  Net::DNS::APL::ApItem objects can be printed using
the string method.

              print $ap->string."\n";		
    }
