A syntax error in readme

https://github.com/Azure/azure-event-hubs-node/blob/3be0b729312e506720e323bdc94172d341fb128e/send_receive/README.md#example-3---create-a-sender-v1

var EventHubClient = require('azure-event-hubs').Client;

var client = EventHubClient.fromConnectionString('Endpoint=sb://my-servicebus-namespace.servicebus.windows.net/;SharedAccessKeyName=my-SA-name;SharedAccessKey=my-SA-key', 'myeventhub')
client.open()
       .then(function() {
        client.createSender();
      })
      .then(function (tx) {
        tx.on('errorReceived', function (err) { console.log(err); });
        tx.send({ contents: 'Here is some text sent to partition key my-pk.' }, 'my-pk'); 
      });

it should be

       .then(function() {
        return client.createSender();
      })

Btw, createSender v1 does not work properly, you can input whatever num in postion 'my-pk', and this function will send the message to a random partition.

I put '200' in the second param postion, and it just sended my message to partition 1.

CreateSender v2 is ok.

Sorry for my bad grammar.

Thanks for reporting this issue. We have a new preview version "0.1.0" of the event hubs client. This client was re-written from scratch. Please try the new version and let us know if you still see issues. You can find examples over here.
