`.stream(cb)` method

Just as an idea: The parser could do much more when it would actually get a stream of data. This would allow the creation of the DOM while IO is happening, which will speed up initial loading (and more stuff could be done inside of DomHandler).

There is already a WritableStream.js file shipped with htmlparser2 (it’s accessible via require("htmlparser2").WritableStream) that pretty much solves all problems. The implementation of the cheerio method could look like this:

cheerio.createWritableStream = function(cb, options){
  var handler = new DomHandler(function(dom){ cb(cheerio(dom)); }, options);
  return new WritableStream(handler, options);
};

looking back at my example, I kind of think adding URL fetching functionality is a bit leaky (do we then support headers, what kind of request methods, etc).

It would be nice to add a streaming interface though, as @fb55 did with cornet. Perhaps more along the lines of:

var $ = cheerio.stream();
minreq.get("http://github.com/fb55").pipe($)
$.on(...)
