Refactoring

In an attempt to make the serialization code more user friendly, I'm in the process of changing the internal model to support a single user routine that:

a) handles both serializing and de-serializing
b) simplifies the API to store/retrieve to the DAO (currently the CkptByteArray)
c) provides extensibility for the DAO, permitting various means of encoding objects within CKPT (raw byte data, compressed data, XML, etc)

Example code and documentation should change very little - hopefully the removal of the deserialize() proc, a different prototype for serialize() and some macros for dynamic type registration and the like.
