   Ready for merge I think, tests need to be changed since I added tags which 
weren't previously being returned. I couldn't really come up with a 
ready-to-use example vs. the previous version since it is so limited that it 
really only did one thing, but I did hack it to try with the sever and client 
examples I will post here and it didn't work well at all, so yes this PR is an 
improvement.
   
   Server example:
   ```julia
   const {default: Agent, ContextManager} = require('skywalking');
   
   Agent.start({
     serviceName: '',
     serviceInstance: '',
     collectorAddress: '',
     authorization: '',
     maxBufferSize: 1000,
   });
   
   const http = require('http');
   
   let count = 0;
   
   const server = http.createServer(function (req, res) {
     if (count++ & 1)
       res.writeHead(404, {'Content-Type': 'text/html'});
   
     res.write('Hello World...\n');
   
     res.end();
   }).listen(8000);
   ```
   
   Client example:
   ```julia
   const {default: Agent, ContextManager} = require('skywalking');
   
   Agent.start({
     serviceName: '',
     serviceInstance: '',
     collectorAddress: '',
     authorization: '',
     maxBufferSize: 1000,
   });
   
   var http = require('http');
   
   callback = function(response) {
     var str = '';
   
     response.on('data', function (chunk) {
       str += chunk;
     });
   
     response.on('end', function () {
       console.log(str);
     });
   }
   
   ContextManager.withSpan(ContextManager.current.newLocalSpan('local'), () => {
     http.request({host: 'localhost', path: '/1', port: '8000', methof: 'GET'}, 
callback).end();
     http.request({host: 'localhost', path: '/2', port: '8000', methof: 'GET'}, 
callback).end();
     http.request({host: 'localhost', path: '/3', port: '8000', methof: 'GET'}, 
callback).end();
   });
   
   setTimeout(() => null, 2500);  // allow time for BG update
   ```
