This installs Anaconda 3 with Jupyter Notebook installed and is based on the Image published by Continuum Analytics on Dockerhub - but without having to call the install code listed there. In addition to the commands listed for the underlying Image (continuumio/anaconda3) the additional argument `--NotebookApp.token=''` is passed to disable the token requirement. This makes the notebook server somewhat "open", which is why it's recommedned to implement additional security/authentication measures.
