title: can't remove records in mongodb
body: <p>I'm trying to remove all the records in my mongodb collection. But when I check to see if it is empty all the records are still there.</p>
  
  <pre><code>var database = mongoose.connect('localhost','news');
  Article.find(function(err,articles){
      Article.remove(articles);
  });
  
  Article.find(function(err,articles){
      if(!err){
          console.log(articles);
      }else{
          console.log(err);
      }
  })
  console.log(database);
  </code></pre>
