push function

Latest dockertest::launch is really nice in that grabs relevant name, finds running machine and starts image. i wonder about an equivalent for pushing to/pulling from dockerhub. Not a big deal, but would complete functionality in dockertest. Currently to push we need to do something like

 eval "$(docker-machine env mem6GB)" 
docker login
 docker push traitecoevo/successional_diversity

This is a great idea.

I'm actually thinking of revisiting the entire dockertest command line tool though; thinking that all it really needs to the ability to inject appropriate arguments into a command line (aside from the accessing of different machines). So I'm going to hold off on this until I can work my head around what is needed.
