Experiment with golang without polluting your local

1. install docker ... really, you need to look at containers !!!

2. docker pull golang

3. pretend we have go installed

       echo 'alias go="docker run --rm -v "$PWD":/usr/src/myapp -w /usr/src/myapp golang go "' >> ~/.bash_profile
       source ~/.bash_profile
