Generate cryptographic signatures for objects
ObjectSignature is an abstract base class that you can inherit from in order to allow your objects to generate unique cryptographic signatures.
The method used to generate the signature is based on Storable and DigestMD5. The object is fed to Storablenfreeze to get a string, which is then passed to DigestMD5md5_hex to get a unique 32 character hexadecimal signature.
