stringifyStream()

empty input stream should output a stream of an empty array.

var stringify = json.stringifier( {} ) ;

} ) ;

stream.on( 'end' , function( data ) {

when the input stream push some object, the output stream should push an array of object.

parseStream()

empty stream (i.e.: "[]").
