Named Parsers and Writers

[James M Snell <ja...@gmail.com>]

One of the goals I've been working towards is the ability to output and
parse Atom from alternative formats.  For instance, we have a JSON
rendering of Atom we've been working on.  There's also an RDF rendering.
I've extended Parser and have introduced new Writer interfaces to allow
for this.

For instance, suppose I want to output Atom as JSON...

  Writer writer = WriterFactory.getInstance("json");
  writer.writeTo(feed, outputStream);

Or, RDF

  Writer writer = WriterFactory.getInstance("rdf");
  writer.writeTo(feed, outputStream);

Alternatively, I could new up a Writer

  Writer writer = new JsonWriter();

It would work the same on the parsing side.  Suppose I want to parse
from JSON or RDF

  Parser parser = ParserFactory.getInstance("json");
  parser.parse(...)

  Parser parser = ParserFactory.getInstance("rdf");
  parser.parse(...)

The named parsers implement the exact same API as the default Abdera parser.

If there are no objections, I'll check it in.
