1.) Moved exclusively to Simon's DefaultHandler object for both Transformer

1.)  Moved exclusively to Simon's DefaultHandler object for both Transformer
and SAXParser usage.  DefaultHandler implements the ContentHandler interface
so it can be used where the latter was previously used, also it provides more
functionality.  [1]

2.) Updated the examples and internal code accordingly.

3.) Renamed ExampleFO2PDFUsingSAX to ...Parser to avoid confusion (both use
SAX.)
