Testing tools for jupyter notebook examples and artifacts

Is your feature request related to a problem? Please describe.
Currently, SDG has no way to keep notebook examples and ensure they don't get stale and outdated. The other examples all run as part of the unit test suite in test_examples.py. That may not be possible with a notebook in the same way but we need some similar tools for the jupyter examples.

Describe the solution you'd like
we need some tool / functionality to keep example notebooks and scripts updated and tested and aligned with updates to SDG
