I have like half a diff for this but figured I should ask for clarification before proceeding... I want to add repositories to Diviner books. Specifically, I want to add a `repositoryPHID` field to the `DivinerLiveBook` class... mainly for the purpose of providing more context.
My understanding of Diviner is limited, but I think that documentation for a book should always come from a single repository? If this is not the case then we would need to move this field to `DivinerLiveAtom` or `DivinerLiveSymbol` (I don't really understand the differences between these classes).
