Consider switching FWSerializable to monty serialization

[computron]

FWSerializable was written before there was a robust serialization package in monty. Now that the latter contains an officially supported serialization package, consider switching FWSerializable to monty serialization.

Or at least make FWSerializable a subclass of monty's serialization if possible.

Will help consistency with monty and other codes we develop.

This is something I'm considering implementing.

One thing we will lose is the class redirection available with FWSerializeable. Is that ok?

[computron]

I think the class redirection is actually pretty important - we do move things around from time to time and FireWorks workflows are intended to be pretty "permanent".

It might be easier to have FWSerializable subclass MSONable?
