binary object serializer

An object serializer takes an object graph as input and
answers a binary array.


What is good with the Ma Serializer


that it works with different Squeak versions. Fuel is tied to
particular Squeak versions. That means the Fuel object you get from
Squeak 4.6. is not guaranteed to load in 5.1. For Ma Serializer this
is the case.
