=head1 SYNOPSIS

=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";
