title: Set Multiple properties to an edge in titan using Java API
body: <p>I want to set multiple properties to the same edge. </p>
  
  <pre><code>tialVertex.addEdge("temp",headVertex).setProperty("key1", "value1");
  </code></pre>
  
  <p>The above command sets only one key-value pair. If I use it again, lets say for  "key2","value2", it will create another edge with the same label(temp) between same vertex instead of appending key-value pair to the edge.</p>
  
  <p>To put together I want one edge having to or more properties(<strong>"key1":"value1"</strong> , <strong>"key1":"value1"</strong>....)</p>
  
  <p>Please help me.</p>
