text: Title: Add docker container(s) to help run examples
  Body: **Is your feature request related to a problem? Please describe.**
  The friction to getting the examples up and running is installing the dependencies. A docker container with them already provided would reduce friction for people to get started with Hamilton.
  
  **Describe the solution you'd like**
  1. A docker container, that has different python virtual environments, that has the dependencies to run the examples.
  2. The container has the hamilton repository checked out -- so it has the examples folder.
  3. Then using it would be:
  
  - docker pull image
  - docker start image
  - activate python virtual environment
  - run example
  
  **Describe alternatives you've considered**
  Not doing this.
  
  **Additional context**
  This was a request from a Hamilton talk.
