Task: Atek Database (ADB) features

[pfrazee]

ADB currently has a simple subset of features, including table schema registration and basic CRUD. It also needs:

• More complex queries with conditions
• Automated property indexing
• Utilities for querying multiple databases
• Change events
• View indexing (trail input DBs for changes and produce computed views)
• Atomic/transactional updates

Ranger's https://github.com/RangerMauve/hyperbeedeebee has a couple of these features implemented and might make sense to use for this as a shared core
