Create robust, multi-task document management interface

[x0xMaximus]

Allow administrators to clearly import documents or select a rule for document import to occur across a range of different task types and manage any associated tasks that must occur in parallel with document import (like pubtator loading)

[andrewsu]

per Max's suggestion, implement these as jupyter notebooks instead of admin interface.

per Ginger's suggestion, focus on how to get new documents/quests in, and how to get data out.
