/**
This class implements a Serializer device, whereby data is
serialized and sent to an output binary file in a system-
independent way.
All bytes and integers are written as int's. Strings are
written as characters prepended by the length of the string.
Boolean values are written using a special pattern.

The new version uses a stringstream (not a file stream)
