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.
new file: lib/serialisation/BaseIO.h
modified: lib/serialisation/BinaryIO.h
modified: lib/serialisation/Serialisation.h
modified: lib/serialisation/TextIO.h
modified: lib/serialisation/XmlIO.h
The test uses the Xml, Binary and Text formats as well as cout << Object.
