Ruby Serial

Library serializing Ruby objects, optimized in many ways:
* Fast and small: use MessagePack (binary compact storage) and don't serialize twice the same object
* Independent of Ruby version: dump and load data across different versions
* Keep shared objects: if an object is shared by others, serialization still keeps the reference and does not duplicate objects in memory
* Gives the ability to fine tune which attributes of your objects are to be serialized (defaults to all)
* Keeps backward compatibility with previously serialized versions
* Has callbacks support to fine tune the serialization process
* Can serialize objects having reference cycles (self-contained Arrays, Hashes, objects...)
