Make repo more useable

[dataminion]

In my fork I have created two branches;

• win-demo
• mac-demo

These branches are respectively;

• an extract of the code previously in this repo
• the vast folder from the main oa repo

I would like to request that two branches get created so that I can PR my branches in, I believe that this will eliminate significant confusion for people coming to try to use the demo in the future.
