[Documentation]: I don't understand how to read HERD

[bendichter]

What would you like changed or added to the documentation and why?

The HERD documentation simply says I should run er_read = HERD.from_zip(path='./HERD.zip'). OK? Then I get an object that renders like this in a Jupyter notebook:

All of the expandable items are empty. I don't see how to access any of the information. @rly's comment here illustrates a much more practical way to access HERD information

Do you have any interest in helping write or edit the documentation?

Yes.

Thanks for creating the issue. When I was making that example, I was also confused about how to read HERD data. I agree - we need to improve the docs and better integrate it with PyNWB.
