self.summary should return an object

I think self.summary should return a Summary object that has an HTML representation. Is this something you thought about already? If not, I'd love to do it.

I think that would be good. I expect the best majority of users to be using a notebook, but some might use the command line. It could be good to offer plain text (ie the current situation) or HTML?

But seeing that aside, yes, I think a html output would be great 👍🏻
