####Synopsis
Just a simplified version of http server , ONLY "GET" method supported!
####Usage
You could use it like that:
var server = new IHttpServer(function(req, res){
  //debug('method: ' + req.method);
  //debug('path: '  + req.path);
  //debug('version: ' + req.version);
  var content = 'hello,world';
  res.writeHead(200, {
    'content-type' : 'text/plain'
  });
  res.end(content);
});
server.listen(ADDRESS, PORT, BACK_LOG);
####Benchmark Compared with Node's classical "hello,world"
siege -c 50 -r 10000 -b XXX:3459/

####Note
This's just an experiment , maybe there are some bugs,
if you want to use it in production ,you SHOULD consider it seriously...
