[jdom-interest] new sax-based utils

[Joseph Bowbeer]

Notice:  Improvements and additions to samples.sax

  http://cvs.jdom.org/cgi-bin/viewcvs.cgi/jdom/samples/sax/


Improvements:

  LexicalHandler support added to XMLFilterBase and XMLWriter.


Additions:

  XMLReaderBase class and DocumentReader implementation.


XMLReaderBase is designed for folks who want to wrap one of their classes in
an XMLReader skin.

DocumentReader, which extends XMLReaderBase, turns a JDOM Document into an
XMLReader (using SAXOutputter to do the actual work).

DocumentReader is useful when you have a JDOM Document that you want to
hand-off to a consumer that accepts an XMLReader.  When the consumer calls
the DocumentReader's parse method, the DocumentReader invokes SAXOutputter
to transmit the source document as SAX events.

(One could also imagine creating an InputSource wrapper for a JDOM
Document.)
