change to Schema.pm

[Graham B. <gb...@po...>]

I have just uploaded to CVS the following change. It's mainly performance
tweaks, but it does also allow a ::Entry object to be passed directly.

Also, The API should now really be

  $schema = Net::LDAP::Schema->new;
  $schema->parse( $entry ) or die $schema->error;

But of course the previous API of ->new( $entry ) still works as it
did, you just cannot access the error string.

Graham.
