Allow users to inventory + edit their dataset(s)

[jeff1evesque]

We will provide each user the ability to inventory each collection of datasets they have permission to access. Then, we will nest the corresponding documents under each collection. The user will be able to expand the corresponding document, and make inline edits, as they find fit, and resubmit into the database. This will be accomplished using the react-json-view package, which was introduced in #3191.
