Additional onm.Address test vectors...
Hunting for a bug somewhere in onm.Address by writing tests...
... I'm thinking that onm.Address.createSubpathAddress drops key(s)?
Fix for issue #25.
Expose a bug in onm.Addresss.createSubpathAddress.
Expose and reproduce issue #26: bogus key replication in onm.Address.createHumanReadableString.
