Get rid of Image
  - Replace with operations on Matrix and cv helper js functions


 - Matrix doesn't need to be eventemitter:

 instead create a cv.MatrixBuffer class that is an event emitter, and wraps matrix in js

 var mat = cv.readImage('foo.jpg');
 
 //shortcut for cascade classifier
 mat.detectFaces('data.xml', function(err, faces){
 	for (var i=0;i<faces.length; i++){
	    var x = faces[i]
	    mat.ellipse(x.x + x.width/2, x.y + x.height/2, x.width/2, x.height/2);
	}
 });




var s = new opencv.ImageStream()

s.on('load', function(mat){
	cv.writeImage(mat, filename, function(err){});
})

request.get('foo').pipe(s);
