derived relationship. Have Text/Binary/Xml versions of
Reader & Writer.
Any new Reader/Writer class inheriting the interface can give object serialisation
to any desired format now.

The test uses the Xml, Binary and Text formats as well as cout << Object.
Test_serialisation has an example of *code* *free* object serialisation
to both ostream and to XML using macro magic.
Implementing TextReader/TextWriter, YAML, JSON etc.. should be trivial
and we can use configure time options to select the default "Reader" typedef.
Present done with
"using XMLPolicy::Reader"
to pick up the default serialisation strategy.
