title: routing 2 urls to 1 handler
body: <p>I'm trying to implement some sort of API on tornado and I have such question:
  is it possible to route two urls to one handler separating by method.</p>
  
  <pre><code>class Handler():
     def get(self):
         #only for the first url
     def post(self):
         #only for the secornd url
  handlers = [
     (r"/url1",Handler), #only GET are allowed
     (r"/url2",Handler), #only POST are allowed
  ]
  </code></pre>
  
  <p>So if someone trying to send POST to the first url he should see error message</p>
