add instructions for running notebooks locally

[mscarey]

This process seems to have changed since I replaced setup.py with setup.cfg.

I had to do this:

1. Use venv to create a virtual environment with a unique name (no other virtual environment on the computer has the same name).

   python -m venv ausvenv

2. Install both the regular requirements and the dev requirements.

python -m pip install -r requirements.txt
python -m pip install -r requirements-dev.txt

2. Register the virtual environment with ipykernel.

   python -m ipykernel install --user --name=ausvenv

3. Start a conda environment.

   conda activate

4. Activate conda development mode in the authorityspoke directory.

   conda develop .

5. Start Jupyter Notebook

   jupyter notebook

6. In the web browser, navigate to the notebooks folder and open one of the .ipynb files.
