Adding @Oliver-I

Looks good

[germanattanasio]

@stevenpkg can you update the README.md with the new instructions?
I would like for you to also test this with an app running in the IBM Cloud rather than locally so that we can be sure it will work as expected

[stevenpkg]

@germanattanasio you can test a dev version here

http://watson-assistant-intermediate-dev.mybluemix.net/

What changes to the readme would you like to see done?

[germanattanasio]

If you can say that this demo is using Assistant V2(link to the documentation) and to access the V1 use this url: v1.1.0

[stevenpkg]

@germanattanasio will make the changes you requested. Also can we keep a V1 snapshot/version so anyone that want to look at V1 code can.

[Oliver-I]

@stevenpkg I have updated the readme file on your branch.

@germanattanasio we always test on the cloud using dev UIs to see how the system reacts within the cloud.
