    Update client.js
    
    Following the docs present in [here](https://github.com/apache/tinkerpop/blob/master/gremlin-javascript/src/main/javascript/gremlin-javascript/README.md), getting started with Gremlin throws the following error:
    
    ```bash
    /home/node/node_modules/gremlin/lib/driver/client.js:49
    if (this._options.processor === 'session') {
    TypeError: Cannot read property 'processor' of undefined
    at new Client (/home/node/node_modules/gremlin/lib/driver/client.js:49:23)
    at new DriverRemoteConnection (/home/node/node_modules/gremlin/lib/driver/driver-remote-connection.js:53:20)
    ```
    
    So, I suggest that we can pass a default empty object to the client constructor, what do you think?
